Title = {{Denoising human cardiac diffusion tensor magnetic
resonance images using sparse representation combined
with segmentation}},
Journal = {Physics in Medicine and Biology},
Volume = {54},
Number = {6},
Pages = {1435--1456},
abstract = {Cardiac diffusion tensor magnetic resonance imaging
(DT-MRI) is noise sensitive, and the noise can induce
numerous systematic errors in subsequent parameter
calculations. This paper proposes a sparse
representation-based method for denoising cardiac
DT-MRI images. The method first generates a dictionary
of multiple bases according to the features of the
observed image. A segmentation algorithm based on
nonstationary degree detector is then introduced to
make the selection of atoms in the dictionary adapted
to the image's features. The denoising is achieved by
gradually approximating the underlying image using the
atoms selected from the generated dictionary. The
results on both simulated image and real cardiac DT-MRI
images from ex vivo human hearts show that the proposed
denoising method performs better than conventional
denoising techniques by preserving image contrast and
fine structures.},

prevalent genetic disorder whose manifestations include
developmental disability and sometimes mental
retardation. The few studies that have examined brain
morphology in different samples from this population
have found similar general patterns, mostly using
region of interest measures. We employed voxel-based
techniques to concurrently examine specific morphologic
changes in multiple brain tissue measures. Results were
similar to previous findings of volumetric reductions
in the posterior brain. They also extended them in two
ways. First, our methods provided greater specificity
in the localization of changes detected. Second, the
combination of our measures of gray and white matter
along with cerebrospinal fluid volume and fractional
anisotropy, which indicates the structure of white
matter, showed a posterior displacement of and
morphologic changes to the corpus callosum in affected
children.},

Pages = {e159},
abstract = {Structurally segregated and functionally specialized
regions of the human cerebral cortex are interconnected
by a dense network of cortico-cortical axonal pathways.
By using diffusion spectrum imaging, we noninvasively
mapped these pathways within and across cortical
hemispheres in individual human participants. An
analysis of the resulting large-scale structural brain
networks reveals a structural core within posterior
medial and parietal cerebral cortex, as well as several
distinct temporal and frontal modules. Brain regions
within the structural core share high degree, strength,
and betweenness centrality, and they constitute
connector hubs that link all major structural modules.
The structural core contains brain regions that form
the posterior components of the human default network.
Looking both within and outside of core regions, we
observed a substantial correspondence between
structural connectivity and resting-state functional
connectivity measured in the same participants. The
spatial and topological centrality of the core within
cortex suggests an important role in functional
integration.},

Cerebral Cortex Using In Vivo Diffusion Tensor Imaging
Tractography}},
Journal = {Cereb. Cortex},
Pages = {bhn102},
abstract = {The characterization of the topological architecture
of complex networks underlying the structural and
functional organization of the brain is a basic
challenge in neuroscience. However, direct evidence for
anatomical connectivity networks in the human brain
remains scarce. Here, we utilized diffusion tensor
imaging deterministic tractography to construct a
macroscale anatomical network capturing the underlying
common connectivity pattern of human cerebral cortex in
a large sample of subjects (80 young adults) and
further quantitatively analyzed its topological
properties with graph theoretical approaches. The
cerebral cortex was divided into 78 cortical regions,
each representing a network node, and 2 cortical
regions were considered connected if the probability of
fiber connections exceeded a statistical criterion. The
topological parameters of the established cortical
network (binarized) resemble that of a "small-world"
architecture characterized by an exponentially
truncated power-law distribution. These characteristics
imply high resilience to localized damage. Furthermore,
this cortical network was characterized by major hub
regions in association cortices that were connected by
bridge connections following long-range white matter
pathways. Our results are compatible with previous
structural and functional brain networks studies and
provide insight into the organizational principles of
human brain anatomical networks that underlie
functional states.},

Title = {Three-dimensional water diffusion in impermeable
cylindrical tubes: theory versus experiments},
Journal = {NMR IN BIOMEDICINE},
Volume = {21},
Pages = {888898},
abstract = {Characterizing diffusion of gases and liquids within
pores is important in understanding numerous transport
processes and affects a wide range of practical
applications. Previous measurements of the pulsed
gradient stimulated echo (PGSTE) signal attenuation,
E(q), of water within nerves and impermeable
cylindrical microcapillary tubes showed it to be
exquisitely sensitive to the orientation of the applied
wave vector, q, with respect to the tube axis in the
high-q regime. Here, we provide a simple
three-dimensional model to explain this angular
dependence by decomposing the average propagator, which
describes the net displacement of water molecules, into
components parallel and perpendicular to the tube wall,
in which axial diffusion is free and radial diffusion
is restricted. The model faithfully predicts the
experimental data, not only the observed diffraction
peaks in E(q) when the diffusion gradients are
approximately normal to the tube wall, but their sudden
disappearance when the gradient orientation possesses a
small axial component. The model also successfully
predicts the dependence of E(q) on gradient pulse
duration and on gradient strength as well as tube inner
diameter. To account for the deviation from the narrow
pulse approximation in the PGSTE sequence, we use
Callaghans matrix operator framework, which this study
validates experimentally for the first time. We also
show how to combine average propagators derived for
classical one-dimensional and two-dimensional models of
restricted diffusion (e.g. between plates, within
cylinders) to construct composite three-dimensional
models of diffusion in complex media containing pores
(e.g. rectangular prisms and/ or capped cylinders)
having a distribution of orientations, sizes, and
aspect ratios. This three-dimensional modeling
framework should aid in describing diffusion in
numerous biological systems and in a myriad of
materials sciences applications.},

\{{D}{T}-{MRI}\} with applications to segmentation of
isolated rat hippocampi},
Journal = {IEEE Transactions on Medical Imaging},
Volume = {26},
Number = {11},
Pages = {1537-1546},
abstract = {In this paper, we present novel algorithms for
statistically robust interpolation and approximation of
diffusion tensors-which are symmetric positive definite
(SPD) matrices-and use them in developing a significant
extension to an existing probabilistic algorithm for
scalar field segmentation, in order to segment
diffusion tensor magnetic resonance imaging (DT-MRI)
datasets. Using the Riemannian metric on the space of
SPD matrices, we present a novel and robust higher
order (cubic) continuous tensor product of -splines
algorithm to approximate the SPD diffusion tensor
fields. The resulting approximations are appropriately
dubbed tensor splines. Next, we segment the diffusion
tensor field by jointly estimating the label (assigned
to each voxel) field, which is modeled by a Gauss
Markov measure field (GMMF) and the parameters of each
smooth tensor spline model representing the labeled
regions. Results of interpolation, approximation, and
segmentation are presented for synthetic data and real
diffusion tensor fields from an isolated rat
hippocampus, along with validation. We also present
comparisons of our algorithms with existing methods and
show significantly improved results in the presence of
noise as well as outliers. },

region-of-interest (ROI) approaches used to analyse the

difficulties. Taking the example of the genu of the

we discuss the difficulties in attempting to replicate
a voxel-based finding of reduced anisotropy using two
ROI methods. Firstly we consider conventional ROIs;
secondly, we present a novel tractography-based
approach. The problems of both methods are explored,
particularly of high variance and ROI definition. The
potential benefits of the tractographic method for

commonly used streamline approach is adapted to exploit
the uncertainty in the orientation of the principal
direction of diffusion defined for each image voxel.
Running the streamline process repeatedly using Monte
Carlo methods to exploit this inherent uncertainty
generates maps of connection probability. Uncertainty
is defined by interpreting the shape of the diffusion
orientation profile provided by the diffusion tensor in
terms of the underlying microstructure. RESULTS: Two
candidates for describing the uncertainty in the
diffusion tensor are proposed and maps of probability
of connection to chosen start points or regions are
generated in a number of major tracts. CONCLUSION: The
methods presented provide a generic framework for
utilizing streamline methods to generate probabilistic
maps of connectivity.},

One of the main drawbacks of reliable fiber mapping is
the correct detection of the orientation of multiple

method based on linear data structures is proposed to
define the fiber paths regarding their diffusivity.
Another advantage of the proposed method is that the
analysis is applied on entire brain diffusion tensor

the method will be developed as a rapid fiber

abstract = {Functional imaging with positron emission tomography
and functional MRI has revolutionized studies of the
human brain. Understanding the organization of brain
systems, especially those used for cognition, remains
limited, however, because no methods currently exist
for noninvasive tracking of neuronal connections
between functional regions [Crick, F. \& Jones, E.
(1993) Nature (London) 361, 109-110]. Detailed
connectivities have been studied in animals through
invasive tracer techniques, but these invasive studies
cannot be done in humans, and animal results cannot
always be extrapolated to human systems. We have
developed noninvasive neuronal fiber tracking for use
in living humans, utilizing the unique ability of MRI
to characterize water diffusion. We reconstructed fiber
trajectories throughout the brain by tracking the
direction of fastest diffusion (the fiber direction)
from a grid of seed points, and then selected tracks
that join anatomically or functionally (functional MRI)
defined regions. We demonstrate diffusion tracking of
fiber bundles in a variety of white matter classes with
examples in the corpus callosum, geniculo-calcarine,
and subcortical association pathways. Tracks covered
long distances, navigated through divergences and tight
curves, and manifested topological separations in the
geniculo-calcarine tract consistent with tracer studies
in animals and retinotopy studies in humans.
Additionally, previously undescribed topologies were
revealed in the other pathways. This approach enhances
the power of modern imaging by enabling study of fiber
connections among anatomically and functionally defined
brain regions in individual human subjects.},

Title = {Resolving crossings in the corticospinal tract by
two-tensor streamline tractography: {M}ethod and
clinical assessment using f{MRI}.},
Journal = {Neuroimage},
abstract = {An inherent drawback of the traditional diffusion
tensor model is its limited ability to provide detailed
information about multidirectional fiber architecture
within a voxel. This leads to erroneous fiber
tractography results in locations where fiber bundles
cross each other. This may lead to the inability to
visualize clinically important tracts such as the
lateral projections of the corticospinal tract. In this
report, we present a deterministic two-tensor eXtended
Streamline Tractography (XST) technique, which
successfully traces through regions of crossing fibers.
We evaluated the method on simulated and in vivo human
brain data, comparing the results with the traditional
single-tensor and with a probabilistic tractography
technique. By tracing the corticospinal tract and
correlating with fMRI-determined motor cortex in both
healthy subjects and patients with brain tumors, we
demonstrate that two-tensor deterministic streamline
tractography can accurately identify fiber bundles
consistent with anatomy and previously not detected by
conventional single-tensor tractography. When compared
to the dense connectivity maps generated by
probabilistic tractography, the method is
computationally efficient and generates discrete
geometric pathways that are simple to visualize and
clinically useful. Detection of crossing white matter
pathways can improve neurosurgical visualization of
functionally relevant white matter areas.},

investigate signal behavior for a single fiber,

Title = {{What are lightness illusions and why do we see them?}},
Journal = {PLoS computational biology},
Volume = {3},
Number = {9},
Pages = {1790--800},
abstract = {Lightness illusions are fundamental to human
perception, and yet why we see them is still the focus
of much research. Here we address the question by
modelling not human physiology or perception directly
as is typically the case but our natural visual world
and the need for robust behaviour. Artificial neural
networks were trained to predict the reflectance of
surfaces in a synthetic ecology consisting of 3-D
"dead-leaves" scenes under non-uniform illumination.
The networks learned to solve this task accurately and
robustly given only ambiguous sense data. In
addition--and as a direct consequence of their
experience--the networks also made systematic "errors"
in their behaviour commensurate with human illusions,
which includes brightness contrast and
assimilation--although assimilation (specifically
White's illusion) only emerged when the virtual ecology
included 3-D, as opposed to 2-D scenes. Subtle
variations in these illusions, also found in human
perception, were observed, such as the asymmetry of
brightness contrast. These data suggest that
"illusions" arise in humans because (i) natural stimuli
are ambiguous, and (ii) this ambiguity is resolved
empirically by encoding the statistical relationship
between images and scenes in past visual experience.
Since resolving stimulus ambiguity is a challenge faced
by all visual systems, a corollary of these findings is
that human illusions must be experienced by all visual
animals regardless of their particular neural
machinery. The data also provide a more formal
definition of illusion: the condition in which the true
source of a stimulus differs from what is its most
likely (and thus perceived) source. As such, illusions
are not fundamentally different from non-illusory
percepts, all being direct manifestations of the
statistical relationship between images and scenes.},

Journal = {Medical image analysis},
Volume = {12},
Number = {4},
Pages = {427--41},
abstract = {Intra-subject and inter-subject nonlinear registration
based on dense transformations requires the setting of
many parameters, mainly for regularization. This task
is a major issue, as the global quality of the
registration will depend on it. Setting these
parameters is, however, very hard, and they may have to
be tuned for each patient when processing data acquired
by different centers or using different protocols.
Thus, we present in this article a method to introduce
more coherence in the registration by using fewer
degrees of freedom than with a dense registration. This
is done by registering the images only on user-defined
areas, using a set of affine transformations, which are
optimized together in a very efficient manner. Our
framework also ensures a smooth and coherent
transformation thanks to a new regularization of the
affine components. Finally, we ensure an invertible
transformation thanks to the Log-Euclidean polyaffine
framework. This allows us to get a more robust and very
efficient registration method, while obtaining good
results as explained below. We performed a qualitative
and quantitative evaluation of the obtained results on
two applications: first on atlas-based brain
segmentation, comparing our results with a dense
registration algorithm. Then the second application for
which our framework is particularly well suited
concerns bone registration in the lower-abdomen area.
We obtain in this case a better positioning of the
femoral heads than with a dense registration. For both
applications, we show a significant improvement in
computation time, which is crucial for clinical
applications.},

abstract = {Diffusion weighted MR imaging is a powerful tool that
can be employed to study white matter microstructure by
examing the 3D displacement profile of water molecules

gradients along a minimum of 6 directions, second-order
tensors can be computed to model dominant diffusion
processes. However, it has been shown that conventional
DTI is not sufficient to resolve crossing fiber tracts.
More recently, High Angular Resolution Diffusion
Imaging (HARDI) seeks to address this issue by
employing more than 6 gradient directions. In this
paper, we introduce the Tensor Distribution Function
(TDF), a probability function defined on the space of
symmetric and positive definite matrices. Here, fiber
crossing is modeled as an ensemble of Gaussian
diffusion processes with weights specified by the TDF.
Once this optimal TDF is determined, ODF can easily be
computed by analytic integration of the resulting
displacement probability function. Moreover, principal
fiber directions can also be directly derived from the
TDF.},

diffusion {MRI} using a twice-refocused spin echo.},
Journal = {Magn Reson Med},
Volume = {49},
Number = {1},
Pages = {177-82},
abstract = {Image distortion due to field gradient eddy currents
can create image artifacts in diffusion-weighted MR
images. These images, acquired by measuring the
attenuation of NMR signal due to directionally
dependent diffusion, have recently been shown to be
useful in the diagnosis and assessment of acute stroke
and in mapping of tissue structure. This work presents
an improvement on the spin-echo (SE) diffusion sequence
that displays less distortion and consequently improves
image quality. Adding a second refocusing pulse
provides better image quality with less distortion at
no cost in scanning efficiency or effectiveness, and
allows more flexible diffusion gradient timing. By
adjusting the timing of the diffusion gradients, eddy
currents with a single exponential decay constant can
be nulled, and eddy currents with similar decay
constants can be greatly reduced. This new sequence is
demonstrated in phantom measurements and in diffusion
anisotropy images of normal human brain.},

summarizes the main technical developments we have made
to date, which include anisotropic smoothing,
anisotropic interpolation, Bayesian fiber tracking and
automatic fiber bundling. A primary focus of these
techniques is the robustness to noise and partial
volume averaging, the two major hurdles to reliable
fiber tractography. Performance of these techniques has
been comprehensively examined with simulated and in
vivo DTI data, demonstrating improvements in the
robustness and reliability of DTI tractography.},

abstract = {A method is described which seems to be effective for
extracting the abnormal components from the clinical
EEG. The approach involves the use of a set a spatial
patterns which are common to recorded and 'normal' EEGs
and which can account for maximally different
proportions of the combined variances in both EEGs.
These spatial factors are used to decompose the EEG
into orthogonal temporal wave forms which can be judged
by the expert electroencephalographer to be abnormal,
normal or of artifactual origin. The original EEG is
then reconstructed using only the abnormal components
and principal component analysis is used to present the
spatial topography of the abnormal components. The
effectiveness of the method is discussed along with its
value for localization of abnormal sources. It is
suggested, in conclusion, that the approach described
may be optimal for interpretation of the clinical EEG
since it allows what is best in terms of quantitative
analysis of the EEG to be combined with the best that
is available in terms of expert qualitative analysis.},

segmentation of tractography from novel subjects by
extending the spectral clustering solution, stored in
the atlas, using the Nystrom method. We present results
regarding the stability of our method and parameter
choices. Finally we give results from an atlas creation
and automatic segmentation experiment. We demonstrate
that our automatic tractography segmentation identifies
corresponding white matter regions across hemispheres

diffusion information that can be used to estimate the
patterns of white matter connectivity in the human

white matter tractography is examined. The algorithm,
called TEND, uses the entire diffusion tensor to
deflect the estimated fiber trajectory. Simulations and
imaging experiments on in vivo human brains were
performed to investigate the behavior of the
tractography algorithm. The simulations show that the
deflection term is less sensitive than the major
eigenvector to image noise. In the human brain imaging
experiments, estimated tracts were generated in corpus
callosum, corticospinal tract, internal capsule, corona
radiata, superior longitudinal fasciculus, inferior
longitudinal fasciculus, fronto-occipital fasciculus,
and uncinate fasciculus. This approach is promising for
mapping the organizational patterns of white matter in
the human brain as well as mapping the relationship
between major fiber trajectories and the location and
extent of brain lesions.},

tractography of crossing fibers.},

abstract = {MRI tractography is the mapping of neural fiber
pathways based on diffusion MRI of tissue diffusion
anisotropy. Tractography based on diffusion tensor
imaging (DTI) cannot directly image multiple fiber
orientations within a single voxel. To address this
limitation, diffusion spectrum MRI (DSI) and related
methods were developed to image complex distributions
of intravoxel fiber orientation. Here we demonstrate
that tractography based on DSI has the capacity to
image crossing fibers in neural tissue. DSI was
performed in formalin-fixed brains of adult macaque and
in the brains of healthy human subjects. Fiber tract
solutions were constructed by a streamline procedure,
following directions of maximum diffusion at every
point, and analyzed in an interactive visualization
environment (TrackVis). We report that DSI tractography
accurately shows the known anatomic fiber crossings in
optic chiasm, centrum semiovale, and brainstem; fiber
intersections in gray matter, including cerebellar
folia and the caudate nucleus; and radial fiber
architecture in cerebral cortex. In contrast, none of
these examples of fiber crossing and complex structure
was identified by DTI analysis of the same data sets.
These findings indicate that DSI tractography is able
to image crossing fibers in neural tissue, an essential
step toward non-invasive imaging of connectional
neuroanatomy.},

Journal = {NeuroImage},
Volume = {47},
Number = {4},
Pages = {1288--300},
abstract = {The assessment of Diffusion-Weighted MRI (DW-MRI)
fibre-tracking algorithms has been limited by the lack
of an appropriate 'gold standard'. Practical
limitations of alternative methods and physical models
have meant that numerical simulations have become the
method of choice in practice. However, previous
numerical phantoms have consisted of separate fibres
embedded in homogeneous backgrounds, which do not
capture the true nature of white matter. In this paper
we describe a method that is able to randomly generate
numerical structures consisting of densely packed
bundles of fibres, which are much more representative
of human white matter, and simulate the DW-MR images
that would arise from them under many imaging
conditions. User-defined parameters may be adjusted to
produce structures with a range of complexities that
spans the levels we would expect to find in vivo. These
structures are shown to contain many different features
that occur in human white matter and which could
confound fibre-tracking algorithms, such as tract
kissing and crossing. Furthermore, combinations of such
features can be sampled by the random generation of
many different structures with consistent levels of
complexity. The proposed software provides means for
quantitative assessment via direct comparison between
tracking results and the exact location of the
generated fibres. This should greatly improve our
understanding of algorithm performance and therefore
prove an important tool for fibre tracking development.},

abstract = {This paper exploits the idea that each individual
brain region has a specific connection profile to
create parcellations of the cortical mantle using MR
diffusion imaging. The parcellation is performed in two
steps. First, the cortical mantle is split at a
macroscopic level into 36 large gyri using a sulcus
recognition system. Then, for each voxel of the cortex,
a connection profile is computed using a probabilistic
tractography framework. The tractography is performed
from q fields using regularized particle trajectories.
Fiber ODF are inferred from the q-balls using a
sharpening process focusing the weight around the
q-ball local maxima. A sophisticated mask of
propagation computed from a T1-weighted image perfectly
aligned with the diffusion data prevents the particles
from crossing the cortical folds. During propagation,
the particles father child particles in order to
improve the sampling of the long fascicles. For each
voxel, intersection of the particle trajectories with
the gyri lead to a connectivity profile made up of only
36 connection strengths. These profiles are clustered
on a gyrus by gyrus basis using a K-means approach
including spatial regularization. The reproducibility
of the results is studied for three subjects using
spatial normalization.},

real-time interactive fiber tracking, which aims at
providing a rich and intuitive environment for the

executed automatically every time the user acts upon
the application. Particularly, when the volume of
interest from which fiber trajectories are calculated
is moved on the screen, fiber tracking is executed,
even while it is being moved. We present our fiber
tracking tool, which implements the real-time fiber
tracking concept by using the video card's graphics
processing units to execute the fiber tracking
algorithm. Results show that real-time interactive
fiber tracking is feasible on computers equipped with
common, low-cost video cards.},

Pages = {492--502},
abstract = {Geometric models of white matter architecture play an
increasing role in neuroscientific applications of
diffusion tensor imaging, and the most popular method
for building them is fiber tractography. For some
analysis tasks, however, a compelling alternative may
be found in the first and second derivatives of
diffusion anisotropy. We extend to tensor fields the
notion from classical computer vision of ridges and
valleys, and define anisotropy creases as features of
locally extremal tensor anisotropy. Mathematically,
these are the loci where the gradient of anisotropy is
orthogonal to one or more eigenvectors of its Hessian.
We propose that anisotropy creases provide a basis for
extracting a skeleton of the major white matter
pathways, in that ridges of anisotropy coincide with
interiors of fiber tracts, and valleys of anisotropy
coincide with the interfaces between adjacent but
distinctly oriented tracts. The crease extraction
algorithm we present generates high-quality polygonal
models of crease surfaces, which are further simplified
by connected-component analysis. We demonstrate
anisotropy creases on measured diffusion MRI data, and
visualize them in combination with tractography to
confirm their anatomic relevance.},

Volume = {79},

Pages = {440--7},
abstract = {A method is described which seems to be effective for
extracting the abnormal components from the clinical
EEG. The approach involves the use of a set a spatial
patterns which are common to recorded and 'normal' EEGs
and which can account for maximally different
proportions of the combined variances in both EEGs.
These spatial factors are used to decompose the EEG
into orthogonal temporal wave forms which can be judged
by the expert electroencephalographer to be abnormal,
normal or of artifactual origin. The original EEG is
then reconstructed using only the abnormal components
and principal component analysis is used to present the
spatial topography of the abnormal components. The
effectiveness of the method is discussed along with its
value for localization of abnormal sources. It is
suggested, in conclusion, that the approach described
may be optimal for interpretation of the clinical EEG
since it allows what is best in terms of quantitative
analysis of the EEG to be combined with the best that
is available in terms of expert qualitative analysis.},

abstract = {This paper describes a general and flexible Monte-
Carlo simulation framework for diffusing spins that
generates realistic synthetic data for diffusion
magnetic resonance imaging. Similar systems in the
literature consider only simple substrates and their
authors do not consider convergence and parameter
optimization. We show how to run Monte-Carlo
simulations within complex irregular substrates. We
compare the results of the Monte-Carlo simulation to an
analytical model of restricted diffusion to assess
precision and accuracy of the generated results. We
obtain an optimal combination of spins and updates for
a given run time by trading off number of updates in
favor of number of spins such that precision and
accuracy of sythesized data are both optimized. Further
experiments demonstrate the system using a tissue
environment that current analytic models cannot
capture. This tissue model incorporates swelling,
abutting, and deformation. Swelling-induced restriction
in the extracellular space due to the effects of
abutting cylinders leads to large departures from the
predictions of the analytical model, which does not
capture these effects. This swelling-induced
restriction may be an important mechanism in explaining
the changes in apparent diffusion constant observed in
the aftermath of acute ischemic stroke.},

abstract = {We determine a statistic called the (radially)
persistent angular structure (PAS) from samples of the
Fourier transform of a three-dimensional function. The
method has applications in diffusion magnetic resonance
imaging (MRI), which samples the Fourier transform of
the probability density function of particle
displacements. The PAS is then a representation of the
relative mobility of particles in each direction. In
PAS-MRI, we compute the PAS in each voxel of an image.
This technique has biomedical applications, where it
reveals the orientations of microstructural fibres,
such as white-matter fibres in the brain. Scanner time
is a significant factor in determining the amount of
data available in clinical brain scans. Here, we use
measurements acquired for diffusion-tensor MRI, which
is a routine diffusion imaging technique, but extract
richer information. In particular, PAS-MRI can resolve
the orientations of crossing fibres.We test PAS-MRI on
human brain data and on synthetic data. The human brain
data set comes from a standard acquisition scheme for
diffusion-tensor MRI in which the samples in each voxel
lie on a sphere in Fourier space.},

Title = {A method for clustering white matter fiber tracts.},
Journal = {AJNR Am J Neuroradiol},
Volume = {27},
Number = {5},
Pages = {1032-6},
abstract = {BACKGROUND/PURPOSE: Despite its potential for
visualizing white matter fiber tracts in vivo,
diffusion tensor tractography has found only limited
applications in clinical research in which specific
anatomic connections between distant regions need to be
evaluated. We introduce a robust method for fiber
clustering that guides the separation of anatomically
distinct fiber tracts and enables further estimation of
anatomic connectivity between distant brain regions.
METHODS: Line scanning diffusion tensor images (LSDTI)
were acquired on a 1.5T magnet. Regions of interest for
several anatomically distinct fiber tracts were
manually drawn; then, white matter tractography was
performed by using the Runge-Kutta method to
interpolate paths (fiber traces) following the major
directions of diffusion, in which traces were seeded
only within the defined regions of interest. Next, a
fully automatic procedure was applied to fiber traces,
grouping them according to a pairwise similarity
function that takes into account the shapes of the
fibers and their spatial locations. RESULTS: We
demonstrated the ability of the clustering algorithm to
separate several fiber tracts which are otherwise
difficult to define (left and right fornix, uncinate
fasciculus and inferior occipitofrontal fasciculus, and
corpus callosum fibers). CONCLUSION: This method
successfully delineates fiber tracts that can be
further analyzed for clinical research purposes.
Hypotheses regarding specific fiber connections and
their abnormalities in various neuropsychiatric
disorders can now be tested.},

Pages = {368406},
abstract = {This paper exploits the idea that each individual
brain region has a specific connection profile to
create parcellations of the cortical mantle using MR
diffusion imaging. The parcellation is performed in two
steps. First, the cortical mantle is split at a
macroscopic level into 36 large gyri using a sulcus
recognition system. Then, for each voxel of the cortex,
a connection profile is computed using a probabilistic
tractography framework. The tractography is performed
from q fields using regularized particle trajectories.
Fiber ODF are inferred from the q-balls using a
sharpening process focusing the weight around the
q-ball local maxima. A sophisticated mask of
propagation computed from a T1-weighted image perfectly
aligned with the diffusion data prevents the particles
from crossing the cortical folds. During propagation,
the particles father child particles in order to
improve the sampling of the long fascicles. For each
voxel, intersection of the particle trajectories with
the gyri lead to a connectivity profile made up of only
36 connection strengths. These profiles are clustered
on a gyrus by gyrus basis using a K-means approach
including spatial regularization. The reproducibility
of the results is studied for three subjects using
spatial normalization.},

Journal = {NeuroImage},
Volume = {35},

Pages = {1459--72},
abstract = {Diffusion-weighted (DW) MR images contain information
about the orientation of brain white matter fibres that
potentially can be used to study human brain
connectivity in vivo using tractography techniques.
Currently, the diffusion tensor model is widely used to
extract fibre directions from DW-MRI data, but fails in
regions containing multiple fibre orientations. The
spherical deconvolution technique has recently been
proposed to address this limitation. It provides an
estimate of the fibre orientation distribution (FOD) by
assuming the DW signal measured from any fibre bundle
is adequately described by a single response function.
However, the deconvolution is ill-conditioned and
susceptible to noise contamination. This tends to
introduce artefactual negative regions in the FOD,
which are clearly physically impossible. In this study,
the introduction of a constraint on such negative
regions is proposed to improve the conditioning of the
spherical deconvolution. This approach is shown to
provide FOD estimates that are robust to noise whilst
preserving angular resolution. The approach also
permits the use of super-resolution, whereby more FOD
parameters are estimated than were actually measured,
improving the angular resolution of the results. The
method provides much better defined fibre orientation
estimates, and allows orientations to be resolved that
are separated by smaller angles than previously
possible. This should allow tractography algorithms to
be designed that are able to track reliably through
crossing fibre regions.},

abstract = {We propose an integral concept for tractography to
describe crossing and splitting fibre bundles based on
the fibre orientation distribution function (ODF)
estimated from high angular resolution diffusion
imaging (HARDI). We show that in order to perform
accurate probabilistic tractography, one needs to use a
fibre ODF estimation and not the diffusion ODF. We use
a new fibre ODF estimation obtained from a sharpening
deconvolution transform (SDT) of the diffusion ODF
reconstructed from q-ball imaging (QBI). This SDT
provides new insight into the relationship between the
HARDI signal, the diffusion ODF, and the fibre ODF. We
demonstrate that the SDT agrees with classical
spherical deconvolution and improves the angular
resolution of QBI. Another important contribution of
this paper is the development of new deterministic and
new probabilistic tractography algorithms using the
full multidirectional information obtained through use
of the fibre ODF. An extensive comparison study is
performed on human brain datasets comparing our new
deterministic and probabilistic tracking algorithms in
complex fibre crossing regions. Finally, as an
application of our new probabilistic tracking, we
quantify the reconstruction of transcallosal fibres
intersecting with the corona radiata and the superior
longitudinal fasciculus in a group of eight subjects.
Most current diffusion tensor imaging (DTI)-based
methods neglect these fibres, which might lead to
incorrect interpretations of brain functions.},

diffusion tensor (DT) images of the human brain. We
demonstrate that unlike the commonly used ROI-based
methods for population studies, our technique is
sensitive to the local variation of diffusivity
parameters along the fiber tracts. We show the strength
of the proposed approach in identifying the differences
in schizophrenic data compared to controls.
Statistically significant drops in fractional
anisotropy are observed along the genu and bilaterally
in the splenium, as well as an increase in principal
eigenvalue in uncinate fasciculus. This is the first
tract-oriented clinical study in which an anatomical
atlas is used to guide the algorithm.},

Title = {A unified framework for clustering and quantitative
analysis of white matter fiber tracts.},
Journal = {Med Image Anal},
Volume = {12},
Number = {2},
Pages = {191-202},
abstract = {We present a novel approach for joint clustering and
point-by-point mapping of white matter fiber pathways.
Knowledge of the point correspondence along the fiber
pathways is not only necessary for accurate clustering
of the trajectories into fiber bundles, but also
crucial for any tract-oriented quantitative analysis.
We employ an expectation-maximization (EM) algorithm to
cluster the trajectories in a gamma mixture model
context. The result of clustering is the probabilistic
assignment of the fiber trajectories to each cluster,
an estimate of the cluster parameters, i.e. spatial
mean and variance, and point correspondences. The fiber
bundles are modeled by the mean trajectory and its
spatial variation. Point-by-point correspondence of the
trajectories within a bundle is obtained by
constructing a distance map and a label map from each
cluster center at every iteration of the EM algorithm.
This offers a time-efficient alternative to pairwise
curve matching of all trajectories with respect to each
cluster center. The proposed method has the potential
to benefit from an anatomical atlas of fiber tracts by
incorporating it as prior information in the EM
algorithm. The algorithm is also capable of handling
outliers in a principled way. The presented results
confirm the efficiency and effectiveness of the
proposed framework for quantitative analysis of
diffusion tensor MRI.},

Pages = {881-91},
abstract = {Magnetic resonance (MR) diffusion imaging provides a
valuable tool used for inferring structural anisotropy
of brain white matter connectivity from diffusion
tensor imaging. Recently, several high angular
resolution diffusion models were introduced in order to
overcome the inadequacy of the tensor model for
describing fibre crossing within a single voxel. Among
them, q-ball imaging (QBI), inherited from the q-space
method, relies on a spherical Radon transform providing
a direct relationship between the diffusion-weighted MR
signal and the orientation distribution function (ODF).
Experimental validation of these methods in a model
system is necessary to determine the accuracy of the
methods and to optimize them. A diffusion phantom made
up of two textile rayon fibre (comparable in diameter
to axons) bundles, crossing at $90^o$, was designed and
dedicated to ex vivo q-ball validation on a clinical
scanner. Normalized ODFs were calculated inside regions
of interest corresponding to monomodal and bimodal
configurations of underlying structures.
Threedimensional renderings of ODFs revealed monomodal
shapes for voxels containing single-fibre population
and bimodal patterns for voxels located within the
crossing area. Principal orientations were estimated
from ODFs and were compared with a priori structural
fibre directions, validating efficiency of QBI for
depicting fibre crossing. In the homogeneous regions,
QBI detected the fibre angle with an accuracy of $19^o$
and in the fibre-crossing region with an accuracy of
$30^o$.},

Journal = {Electroencephalography and clinical neurophysiology},
Volume = {107},
Number = {5},
Pages = {343--52},
abstract = {OBJECTIVES: The spatio-temporal decomposition (STD)
approach was used to localize the sources of simulated
electroencephalograms (EEGs) to gain experience with
the approach for analyzing real data. METHODS: The STD
approach used is similar to the multiple signal
classification method (MUSIC) in that it requires the
signal subspace containing the sources of interest to
be isolated in the EEG measurement space. It is
different from MUSIC in that it allows more general
methods of spatio-temporal decomposition to be used
that may be better suited to the background EEG.
RESULTS: If the EEG data matrix is not corrupted by
noise, the STD approach can be used to locate multiple
dipole sources of the EEG one at a time without a
priori knowledge of the number of active sources in the
signal space. In addition, the common-spatial-patterns
method of spatio-temporal decomposition is superior to
the eigenvector decomposition for localizing activity
that is ictal in nature. CONCLUSIONS: The STD approach
appears to be able to provide a means of localizing the
equivalent dipole sources of realistic brain sources
and that, even under difficult noise conditions and
only 2 or 3 s of available EEG, the precision of the
localization can be as low as a few mm.},

abstract = {At its simplest, voxel-based morphometry (VBM)
involves a voxel-wise comparison of the local
concentration of gray matter between two groups of

and involves spatially normalizing high-resolution
images from all the subjects in the study into the same
stereotactic space. This is followed by segmenting the
gray matter from the spatially normalized images and
smoothing the gray-matter segments. Voxel-wise
parametric statistical tests which compare the smoothed
gray-matter images from the two groups are performed.
Corrections for multiple comparisons are made using the
theory of Gaussian random fields. This paper describes
the steps involved in VBM, with particular emphasis on
segmenting gray matter from MR images with
nonuniformity artifact. We provide evaluations of the
assumptions that underpin the method, including the
accuracy of the segmentation and the assumptions made

of all trajectories with respect to each cluster
center. Probabilistic assignment of the trajectories to
clusters is controlled by imposing a minimum threshold
on the membership probabilities, to remove outliers in
a principled way. The presented results confirm the
efficiency and effectiveness of the proposed framework
for quantitative analysis of diffusion tensor MRI.},

Title = {Tract-based spatial statistics: Voxelwise analysis of
multi-subject diffusion data},
Journal = {NeuroImage},
Volume = {31},
Pages = {1487-1505},
abstract = {There has been much recent interest in using magnetic
resonance diffusion imaging to provide information
about anatomical connectivity in the brain, by
measuring the anisotropic diffusion of water in white
matter tracts. One of the measures most commonly
derived from diffusion data is fractional anisotropy
(FA), which quantifies how strongly directional the
local tract structure is. Many imaging studies are
starting to use FA images in voxelwise statistical
analyses, in order to localise brain changes related to
development, degeneration and disease. However, optimal
analysis is compromised by the use of standard
registration algorithms; there has not to date been a
satisfactory solution to the question of how to align
FA images from multiple subjects in a way that allows
for valid conclusions to be drawn from the subsequent
voxelwise analysis. Furthermore, the arbitrariness of
the choice of spatial smoothing extent has not yet been
resolved. In this paper, we present a new method that
aims to solve these issues via (a) carefully tuned
non-linear registration, followed by (b) projection
onto an alignment-invariant tract representation (the
mean FA skeleton). We refer to this new approach as
Tract-Based Spatial Statistics (TBSS). TBSS aims to
improve the sensitivity, objectivity and
interpretability of analysis of multi-subject diffusion
imaging studies. We describe TBSS in detail and present
example TBSS results from several diffusion imaging
studies.},

with dynamic queries.},
Journal = {IEEE Trans Vis Comput Graph},
Volume = {11},
Number = {4},
Pages = {419-30},
abstract = {Diffusion Tensor Imaging (DTI) is a magnetic resonance
imaging method that can be used to measure local
information about the structure of white matter within
the human brain. Combining DTI data with the
computational methods of MR tractography,
neuroscientists can estimate the locations and sizes of
nerve bundles (white matter pathways) that course
through the human brain. Neuroscientists have used
visualization techniques to better understand
tractography data, but they often struggle with the
abundance and complexity of the pathways. In this
paper, we describe a novel set of interaction
techniques that make it easier to explore and interpret
such pathways. Specifically, our application allows
neuroscientists to place and interactively manipulate
box or ellipsoid-shaped regions to selectively display
pathways that pass through specific anatomical areas.
These regions can be used in coordination with a simple
and flexible query language which allows for arbitrary
combinations of these queries using Boolean logic
operators. A representation of the cortical surface is
provided for specifying queries of pathways that may be
relevant to gray matter structures and for displaying
activation information obtained from functional
magnetic resonance imaging. By precomputing the
pathways and their statistical properties, we obtain
the speed necessary for interactive question-and-answer
sessions with brain researchers. We survey some
questions that researchers have been asking about
tractography data and show how our system can be used
to answer these questions efficiently.},

analysis.},
Journal = {Neuroimage},
Volume = {45},
Number = {3},
Pages = {832-44},
abstract = {We introduce an automatic method that we call
tract-based morphometry, or TBM, for measurement and
analysis of diffusion MRI data along white matter fiber
tracts. Using subject-specific tractography bundle
segmentations, we generate an arc length
parameterization of the bundle with point
correspondences across all fibers and all subjects,
allowing tract-based measurement and analysis. In this
paper we present a quantitative comparison of fiber
coordinate systems from the literature and we introduce
an improved optimal match method that reduces spatial
distortion and improves intra- and inter-subject
variability of FA measurements. We propose a method for
generating arc length correspondences across
hemispheres, enabling a TBM study of interhemispheric
diffusion asymmetries in the arcuate fasciculus (AF)
and cingulum bundle (CB). The results of this study
demonstrate that TBM can detect differences that may
not be found by measuring means of scalar invariants in
entire tracts, such as the mean diffusivity (MD)
differences found in AF. We report TBM results of
higher fractional anisotropy (FA) in the left
hemisphere in AF (caused primarily by lower lambda(3),
the smallest eigenvalue of the diffusion tensor, in the
left AF), and higher left hemisphere FA in CB (related
to higher lambda(1), the largest eigenvalue of the
diffusion tensor, in the left CB). By mapping the
significance levels onto the tractography trajectories
for each structure, we demonstrate the anatomical
locations of the interhemispheric differences. The TBM
approach brings analysis of DTI data into the
clinically and neuroanatomically relevant framework of
the tract anatomy.},

Journal = {IEEE transactions on visualization and computer

Pages = {1433--40},
abstract = {Visual exploration is essential to the visualization
and analysis of densely sampled 3D DTI fibers in
biological specimens, due to the high geometric,
spatial, and anatomical complexity of fiber tracts.
Previous methods for DTI fiber visualization use
zooming, color-mapping, selection, and abstraction to
deliver the characteristics of the fibers. However,
these schemes mainly focus on the optimization of
visualization in the 3D space where cluttering and
occlusion make grasping even a few thousand fibers
difficult. This paper introduces a novel interaction
method that augments the 3D visualization with a 2D
representation containing a low-dimensional embedding
of the DTI fibers. This embedding preserves the
relationship between the fibers and removes the visual
clutter that is inherent in 3D renderings of the
fibers. This new interface allows the user to
manipulate the DTI fibers as both 3D curves and 2D
embedded points and easily compare or validate his or
her results in both domains. The implementation of the
framework is GPU based to achieve real-time
interaction. The framework was applied to several
tasks, and the results show that our method reduces the
user's workload in recognizing 3D DTI fibers and
permits quick and accurate DTI fiber selection.},

head-only {MR} imaging unit.},
Journal = {Radiology},
Volume = {229},
Number = {3},
Pages = {673-81},
abstract = {PURPOSE: To evaluate the normal brains of adults and
neonates for regional and age-related differences in
apparent diffusion coefficient (ADC) and fractional
anisotropy (FA). MATERIALS AND METHODS: Eight healthy
adults and 20 healthy neonates were examined with a
3.0-T head-only magnetic resonance (MR) imaging unit by
using a single-shot diffusion-tensor sequence. Trace
ADC maps, FA maps, directional maps of the putative
directions of white matter (WM) tracts, and
fiber-tracking maps were obtained. Regions of
interest-eight in WM and one in gray matter (GM)-were
predefined for the ADC and FA measurements. The Student
t test was used to compare FA and ADC between adults
and neonates, whereas the Tukey multiple-comparison
test was used to compare FA and ADC in different brain
regions in the adult and neonate groups. RESULTS: A
global elevation in ADC (P <.001) in both GM and WM and
a reduction in FA (P <.001) in WM were observed in
neonates as compared with these values in adults. In
addition, significant regional variations in FA and ADC
were observed in both groups. Regional variations in FA
and ADC were less remarkable in adults, whereas
neonates had consistently higher FA values and lower
ADC values in the central WM as compared with these
values in the peripheral WM. Fiber tracking revealed
only major WM tracts in the neonates but fibers
extending to the peripheral WM in the adults.
CONCLUSION: There were regional differences in FA and
ADC values in the neonates; such variations were less
remarkable in the adults.},

Journal = {Neuroimage},
Volume = {45},
Number = {2},
Pages = {370-6},
abstract = {MR diffusion tensor imaging (DTI) can measure and
visualize organization of white matter fibre tracts in
vivo. DTI is a relatively new imaging technique, and
new tools developed for quantifying fibre tracts
require evaluation. The purpose of this study was to
compare the reliability of a novel clustering approach
with a multiple region of interest (MROI) approach in
both healthy and disease (schizophrenia) populations.
DTI images were acquired in 20 participants (n=10
patients with schizophrenia: 56+/-15 years; n=10
controls: 51+/-20 years) (1.5 T GE system) with
diffusion gradients applied in 23 non-collinear
directions, repeated three times. Whole brain seeding
and creation of fibre tracts were then performed.
Interrater reliability of the clustering approach, and
the MROI approach, were each evaluated and the methods
compared. There was high spatial (voxel-based)
agreement within and between the clustering and MROI
methods. Fractional anisotropy, trace, and radial and
axial diffusivity values showed high intraclass
correlation (p<0.001 for all tracts) for each approach.
Differences in scalar indices of diffusion between the
clustering and MROI approach were minimal. The
excellent interrater reliability of the clustering
method and high agreement with the MROI method,
quantitatively and spatially, indicates that the
clustering method can be used with confidence. The
clustering method avoids biases of ROI drawing and
placement, and, not limited by a priori predictions,
may be a more robust and efficient way to identify and
measure white matter tracts of interest.},

abstract = {ABSTRACT: BACKGROUND: Current imaging methods such as
Magnetic Resonance Imaging (MRI), Confocal microscopy,
Electron Microscopy (EM) or Selective Plane
Illumination Microscopy (SPIM) yield three-dimensional
(3D) data sets in need of appropriate computational
methods for their analysis. The reconstruction,
segmentation and registration are best approached from
the 3D representation of the data set. RESULTS: Here we
present a platform-independent framework based on Java
and Java 3D for accelerated rendering of biological
images. Our framework is seamlessly integrated into
ImageJ, a free image processing package with a vast
collection of community-developed biological image
analysis tools. Our framework enriches the ImageJ
software libraries with methods that greatly reduce the
complexity of developing image analysis tools in an
interactive 3D visualization environment. In
particular, we provide high-level access to volume
rendering, volume editing, surface extraction, and
image annotation. The ability to rely on a library that
removes the low-level details enables concentrating
software development efforts on the algorithm
implementation parts. CONCLUSIONS: Our framework
enables biomedical image software development to be
built with 3D visualization capabilities with very
little effort. We offer the source code and convenient
binary packages along with extensive documentation at

that aligning directly fiber bundles may solve the

on a statistical model which considers every bundle as
a random diffeomorphic deformation of a common template

abstract = {Magnetic resonance diffusion tensor tractography is a
powerful tool for the non-invasive depiction of the
white matter architecture in the human brain. However,
due to limitations in the underlying tensor model, the
technique is often unable to reconstruct correct
trajectories in heterogeneous fiber arrangements, such
as axonal crossings. A novel tractography method based
on fast marching (FM) is proposed which is capable of
resolving fiber crossings and also permits trajectories
to branch. It detects heterogeneous fiber arrangements
by incorporating information from the entire diffusion
tensor. The FM speed function is adapted to the local
tensor characteristics, allowing in particular to
maintain the front evolution direction in crossing
situations. In addition, the FM's discretization error
is reduced by increasing the number of considered
possible front evolution directions. The performance of
the technique is demonstrated in artificial data and in
the healthy human brain. Comparisons with standard FM
tractography and conventional line propagation
algorithms show that, in the presence of interfering
structures, the proposed method is more accurate in
reconstructing trajectories. The in vivo results
illustrate that the elucidated major white matter
pathways are consistent with known anatomy and that
multiple crossings and tract branching are handled
correctly.},

diffusion tensor imaging (DTI), diminishing the
reliability of the estimated diffusion tensor
information. Studies in this field have so far been
limited mainly to the correction of miniscule

patient motion it is not sufficient to correct for
misregistration between successive shots; the change in
the diffusion-encoding direction must also be accounted
for. This becomes particularly important for multishot
sequences, wherebyin the presence of motioneach shot
is encoded with a different diffusion weighting. In
this study a general mathematical framework to correct
for gross patient motion present in a multishot and
multicoil DTI scan is presented. A signal model is
presented that includes the effect of rotational and
translational motion in the patient frame of reference.
This model was used to create a nonlinear leastsquares
formulation, from which the diffusion tensors were
obtained using a nonlinear conjugate gradient
algorithm. Applications to both phantom simulations and
in vivo studies showed that in the case of gross motion
the proposed algorithm performs superiorly compared to
conventional methods used for tensor estimation.},

abstract = {A new methodology based on Diffusion Weighted Magnetic
Resonance Imaging (DW-MRI) and Graph Theory is
presented for characterizing the anatomical connections
between brain gray matter areas. In a first step, brain
voxels are modeled as nodes of a non-directed graph in
which the weight of an arc linking two neighbor nodes
is assumed to be proportional to the probability of
being connected by nervous fibers. This probability is
estimated by means of probabilistic tissue segmentation
and intravoxel white matter orientational distribution
function, obtained from anatomical MRI and DW-MRI,
respectively. A new tractography algorithm for finding
white matter routes is also introduced. This algorithm
solves the most probable path problem between any two
nodes, leading to the assessment of probabilistic brain
anatomical connection maps. In a second step, for
assessing anatomical connectivity between K gray matter
structures, the previous graph is redefined as a K+1
partite graph by partitioning the initial nodes set in
K non-overlapped gray matter subsets and one subset
clustering the remaining nodes. Three different
measures are proposed for quantifying anatomical
connections between any pair of gray matter subsets:
Anatomical Connection Strength (ACS), Anatomical
Connection Density (ACD) and Anatomical Connection
Probability (ACP). This methodology was applied to both
artificial and actual human data. Results show that
nervous fiber pathways between some regions of interest
were reconstructed correctly. Additionally, mean
connectivity maps of ACS, ACD and ACP between 71 gray
matter structures for five healthy subjects are

abstract = {Magnetic resonance diffusion imaging provides an
exquisitely sensitive probe of tissue microstructure.
Owing to the microscopic length scale of diffusion in
biological tissues, diffusion imaging can reveal
histological architecture irresolvable by conventional
magnetic resonance imaging methods. However, diffusion
imaging methods to date have chiefly been based on
analytical models of the underlying diffusion process.
For example, diffusion tensor imaging assumes
homogeneous Gaussian diffusion within each voxel, an
assumption which is clearly invalid for the vast
majority of the brain at presently achievable voxel
resolutions. In this thesis I developed a diffusion
imaging method capable of measuring the microscopic
diffusion function within each voxel. In contrast to
previous approaches to diffusion imaging, the method
presented here does not require any assumptions on the
underlying diffusion function. The model-independent
approach can resolve complex intravoxel tissue
structure including fiber crossing and fiber divergence
within a single voxel. The method is capable of
resolving not only deep white matter intersections, but
also composite tissue structure at the cortical margin,
and fiber-specific degeneration in neurodegenerative
pathology. In sum, the approach can reveal complex
intravoxel tissue structure previously thought to be
beyond the scope of diffusion imaging methodology.},

associated with asymmetry of the cerebral cortex (grey
matter) and connectivity (white matter). Grey matter
asymmetry, most likely linked to language has been
identified with voxel-based morphometry (VBM) using
T1-weighted images. Differences in white matter
obtained with this technique are less consistent,
probably due to the relative insensitivity of the T1
contrast to the ultrastructure of white matter.
Furthermore, previous VBM studies failed to find
differences related to handedness in either grey or
white matter. We revisited these issues and
investigated two independent groups of subjects with
diffusion-tensor imaging (DTI) for asymmetries in white
matter composition. Using voxel-based statistical
analyses an asymmetry of the arcuate fascicle was
observed, with higher fractional anisotropy in the left
hemisphere. In addition, we show differences related to
handedness in the white matter underneath the
precentral gyrus contralateral to the dominant hand.
Remarkably, these findings were very robust, even when
investigating small groups of subjects. This highlights
the sensitivity of DTI for white matter tissue
differences, making it an ideal tool to study small
patient populations.},

the Radon transform of the radial projection (in

study size, fractional anisotropy (FA), and T2 of
individual white matter tracts. Distinctive features in
FA and T2 were found for the corticospinal tract and
callosal fibers. Hemispheric asymmetry was observed for
the size of white matter tracts projecting to the
temporal lobe. This protocol provides guidelines for

formulated in discrete space (i.e., on a graph) using
combinatorial analogues of standard operators and

abstract = {Whereas high angular resolution reconstruction methods
for diffusion MRI can estimate multiple dominant fibre
orientations within a single imaging voxel, they are
fundamentally limited in certain cases of complex
subvoxel fibre structures, resulting in ambiguous local
orientation distribution functions. In this article we
address the important problem of disambiguating such
complex subvoxel fibre tract configurations, with the
purpose of improving the performance of fibre
tractography. We do so by extending a curve inference
method to distinguish between the cases of curving and
fanning fibre bundles using differential geometric
estimates in a local neighbourhood. The key benefit of
this method is the inference of curves, instead of only
fibre orientations, to model the underlying fibre
bundles. This in turn allows distinct fibre geometries
that contain nearly identical sets of fibre
orientations at a voxel, to be distinguished from one
another. Experimental results demonstrate the ability
of the method to successfully label voxels into one of
the above categories and improve the performance of a
fibre-tracking algorithm.},

Pages = {493-504},
abstract = {Recent advances in diffusion tensor imaging (DTI) have
made it possible to reveal white matter anatomy and to
detect neurological abnormalities in children. However,
the clinical use of this technique is hampered by the
lack of a normal standard of reference. The goal of
this study was to initiate the establishment of a
database of DTI images in children, which can be used
as a normal standard of reference for diagnosis of
pediatric neurological abnormalities. Seven pediatric
volunteers and 23 pediatric patients (age range: 0-54
months) referred for clinical MR examinations, but
whose brains were shown to be normal, underwent
anatomical and DTI acquisitions on a 1.5 T MR scanner.
The white matter maturation, as observed on DTI color
maps, was described and illustrated. Changes in
diffusion fractional anisotropy (FA), average apparent
diffusion constant (ADCave), and T2-weighted (T2W)
signal intensity were quantified in 12 locations to
characterize the anatomical variability of the
maturation process. Almost all prominent white matter
tracts could be identified from birth, although their
anisotropy was often low. The evolution of FA, shape,
and size of the white matter tracts comprised generally
three phases: rapid changes during the first 12 months;
slow modifications during the second year; and relative
stability after 24 months. The time courses of FA,
ADCave, and T2W signal intensity confirmed our visual
observations that maturation of the white matter and
the normality of its architecture can be assessed with
DTI in young children. The database is available online
and is expected to foster the use of this promising
technique in the diagnosis of pediatric pathologies.},

to hop from tract to tract. Still, this method can
provide quantitative information with which to

abstract = {In this paper, we present a robust approach to the
registration of white matter tractographies extracted
from diffusion tensor-magnetic resonance imaging scans.
The fibers are projected into a high dimensional
feature space based on the sequence of their 3-D
coordinates. Adaptive mean-shift clustering is applied
to extract a compact set of representative fiber-modes
(FM). Each FM is assigned to a multivariate Gaussian
distribution according to its population thereby
leading to a Gaussian mixture model (GMM)
representation for the entire set of fibers. The
registration between two fiber sets is treated as the
alignment of two GMMs and is performed by maximizing
their correlation ratio. A nine-parameters affine
transform is recovered and eventually refined to a
twelve-parameters affine transform using an innovative
mean-shift based registration refinement scheme
presented in this paper. The validation of the
algorithm on synthetic intrasubject data demonstrates
its robustness to interrupted and deviating fiber
artifacts as well as outliers. Using real intrasubject
data, a comparison is conducted to other intensity
based and fiber-based registration algorithms,
demonstrating competitive results. An option for
tracking-in-time, on specific white matter fiber
tracts, is also demonstrated on the real data.},

explanation is that game shows use contestants who have
similarities to the viewing population, thereby

prosocial behavior). Using a game show-inspired
paradigm, we show that the interactions between the
ventral striatum and anterior cingulate cortex subserve
the modulation of vicarious reward by similarity,

similarity acts as a proximate neurobiological
mechanism where prosocial behavior extends to unrelated

abstract = {A powerful, non-invasive technique for estimating and
visualizing white matter tracts in the human brain in
vivo is white matter fiber tractography that uses
magnetic resonance diffusion tensor imaging. The
success of this method depends strongly on the
capability of the applied tracking algorithm and the
quality of the underlying data set. However, DTI-based
fiber tractography still lacks standardized validation.
In the present work, a combined fMRI/DTI study was
performed, both to develop a setup for verifying fiber
tracking results using fMRI-derived functional
connections and to explore the limitations of fMRI
based DTI fiber tracking. Therefore, a minor fiber
bundle that features several fiber crossings and
intersections was examined: The striatum and its
connections to the primary motor cortex were examined
by using two approaches to derive the somatotopic
organization of the striatum. First, an fMRI-based
somatotopic map of the striatum was reconstructed,
based on fMRI activations that were provoked by
unilateral motor tasks. Second, fMRI-guided DTI fiber
tracking was performed to generate DTI-based
somatotopic maps, using a standard line propagation and
an advanced fast marching algorithm. The results show
that the fiber connections reconstructed by the
advanced fast marching algorithm are in good agreement
with known anatomy, and that the DTI-revealed
somatotopy is similar to the fMRI somatotopy.
Furthermore, the study illustrates that the combination
of fMRI with DTI can supply additional information in
order to choose reasonable seed regions for generating
functionally relevant networks and to validate
reconstructed fibers.},

distortion due to field gradient eddy currents can
create image artifacts in diffusion-weighted MR images.
These images, acquired by measuring the attenuation of
NMR signal due to directionally dependent diffusion,
have recently been shown to be useful in the diagnosis
and assessment of acute stroke and in mapping of tissue
structure. This work presents an improvement on the
spin-echo (SE) diffusion sequence that displays less
distortion and consequently improves image quality.
Adding a second refocusing pulse provides better image
quality with less distortion at no cost in scanning
efficiency or effectiveness, and allows more flexible
diffusion gradient timing. By adjusting the timing of
the diffusion gradients, eddy currents with a single
exponential decay constant can be nulled, and eddy
currents with similar decay constants can be greatly
reduced. This new sequence is demonstrated in phantom
measurements and in diffusion anisotropy images of
normal human brain. Magn Reson Med 49:177-182, 2003.

Furthermore, changes in diffusion anisotropy under
pathological conditions could alter the results of 3D

of 11 major white matter tracts derived from the DTI
data from 28 normal subjects. Using these probabilistic

fractional anisotropy and mean diffusivity were
performed. Excellent correlation was found between the

abstract = {The present methodological development and the primary
application field originate from diffusion tensor
imaging (DTI), a powerful nuclear magnetic resonance
technique which enables the quantification of
microscopical tissue properties. The current analysis
framework of separate voxelwise regressions is
reformulated as a 3D space-varying coefficient model
(SVCM) for the entire set of diffusion tensor images
recorded on a 3D voxel grid. The SVCM unifies the
three-step cascade of standard data processing
(voxelwise regression, smoothing, interpolation) into
one framework based on B-spline basis functions.
Thereby strength is borrowed from spatially correlated
voxels to gain a regularization effect right at the
estimation stage. Two SVCM variants are conceptualized:
a full tensor product approach and a sequential
approximation, rendering the SVCM numerically and
computationally feasible even for the huge dimension of
the joint model in a realistic setup. A simulation
study shows that both approaches outperform the
standard method of voxelwise regression with subsequent
regularization. Application of the fast sequential
method to real DTI data demonstrates the inherent
ability to increase the grid resolution by evaluating
the incorporated basis functions at intermediate
points. The resulting continuous regularized tensor
field may serve as basis for multiple applications,
yet, ameloriation of local adaptivity is desirable. },

commonly used streamline approach is adapted to exploit
the uncertainty in the orientation of the principal
direction of diffusion defined for each image voxel.
Running the streamline process repeatedly using Monte
Carlo methods to exploit this inherent uncertainty
generates maps of connection probability. Uncertainty
is defined by interpreting the shape of the diffusion
orientation profile provided by the diffusion tensor in
terms of the underlying microstructure. RESULTS: Two
candidates for describing the uncertainty in the
diffusion tensor are proposed and maps of probability
of connection to chosen start points or regions are
generated in a number of major tracts. CONCLUSION: The
methods presented provide a generic framework for
utilizing streamline methods to generate probabilistic
maps of connectivity.},

Journal = {NeuroImage},
Volume = {15},
Number = {1},
Pages = {114-123},
abstract = {We present a method for automated brain tissue
segmentation based on the multi-channel fusion of
diffusion tensor imaging (DTI) data. The method is
motivated by the evidence that independent tissue
segmentation based on DTI parametric images provides
complementary information of tissue contrast to the
tissue segmentation based on structural MRI data. This
has important applications in defining accurate tissue
maps when fusing structural data with diffusion data.
In the absence of structural data, tissue segmentation
based on DTI data provides an alternative means to
obtain brain tissue segmentation. Our approach to the
tissue segmentation based on DTI data is to classify
the brain into two compartments by utilizing the tissue
contrast existing in a single channel. Specifically,
because the apparent diffusion coefficient (ADC) values
in the cerebrospinal fluid (CSF) are more than twice
that of gray matter (GM) and white matter (WM), we use
ADC images to distinguish CSF and non-CSF tissues.
Additionally, fractional anisotropy (FA) images are
used to separate WM from non-WM tissues, as highly
directional white matter structures have much larger
fractional anisotropy values. Moreover, other channels
to separate tissue are explored, such as eigenvalues of
the tensor, relative anisotropy (RA), and volume ratio
(VR). We developed an approach based on the
Simultaneous Truth and Performance Level Estimation
(STAPLE) algorithm that combines these two-class maps
to obtain a complete tissue segmentation map of CSF,
GM, and WM. Evaluations are provided to demonstrate the
performance of our approach. Experimental results of
applying this approach to brain tissue segmentation and
deformable registration of DTI data and spoiled
gradient-echo (SPGR) data are also provided.},

abstract = {PURPOSE: To (a) determine the optimal choice of a
scalar metric of anisotropy and (b) determine by means
of magnetic resonance imaging if changes in diffusion
anisotropy occurred in acute human ischemic stroke.
MATERIALS AND METHODS: The full diffusion tensor over
the entire brain was measured. To optimize the choice
of a scalar anisotropy metric, the performances of
scalar indices in simulated models and in a healthy
volunteer were analyzed. The anisotropy, trace apparent
diffusion coefficient (ADC), and eigenvalues of the
diffusion tensor in lesions and contralateral normal
brain were compared in 50 patients with stroke.
RESULTS: Changes in anisotropy in patients were
quantified by using fractional anisotropy because it
provided the best performance in terms of
contrast-to-noise ratio as a function of
signal-to-noise ratio in simulations. The anisotropy of
ischemic white matter decreased (P = .01). Changes in
anisotropy in ischemic gray matter were not significant
(P = .63). The trace ADC decreased for ischemic gray
matter and white matter (P < .001). The first and
second eigenvalues decreased in both ischemic gray and
ischemic white matter (P < .001). The third eigenvalue
decreased in ischemic gray (P = .001) and white matter
(P = .03). CONCLUSION: Gray matter is mildly
anisotropic in normal and early ischemic states.
However, early white matter ischemia is associated with
not only changes in trace ADC values but also
significant changes in the anisotropy, or shape, of the
water self-diffusion tensor.},

deconvolution: validation using diffusion-weighted
imaging phantom data.}},
Journal = {NeuroImage},
Volume = {42},
Number = {2},
Pages = {617--25},
abstract = {Diffusion-weighted imaging can potentially be used to
infer the connectivity of the human brain in vivo using
fibre-tracking techniques, and is therefore of great
interest to neuroscientists and clinicians. A key
requirement for fibre tracking is the accurate
estimation of white matter fibre orientations within
each imaging voxel. The diffusion tensor model, which
is widely used for this purpose, has been shown to be
inadequate in crossing fibre regions. A number of
approaches have recently been proposed to address this
issue, based on high angular resolution
diffusion-weighted imaging (HARDI) data. In this study,
an experimental model of crossing fibres, consisting of
water-filled plastic capillaries, is used to thoroughly
assess three such techniques: constrained spherical
deconvolution (CSD), super-resolved CSD (super-CSD) and
Q-ball imaging (QBI). HARDI data were acquired over a
range of crossing angles and b-values, from which fibre
orientations were computed using each technique. All
techniques were capable of resolving the two fibre
populations down to a crossing angle of 45 degrees ,
and down to 30 degrees for super-CSD. A bias was
observed in the fibre orientations estimated by QBI for
crossing angles other than 90 degrees, consistent with
previous simulation results. Finally, for a 45 degrees
crossing, the minimum b-value required to resolve the
fibre orientations was 4000 s/mm(2) for QBI, 2000
s/mm(2) for CSD, and 1000 s/mm(2) for super-CSD. The
quality of estimation of fibre orientations may
profoundly affect fibre tracking attempts, and the
results presented provide important additional
information regarding performance characteristics of
well-known methods.},

abstract = {Magnetic resonance diffusion-weighted imaging coupled
with fiber tractography (DFT) is the only non-invasive
method for measuring white matter pathways in the
living human brain. DFT is often used to discover new
pathways. But there are also many applications,
particularly in visual neuroscience, in which we are
confident that two brain regions are connected, and we
wish to find the most likely pathway forming the
connection. In several cases, current DFT algorithms
fail to find these candidate pathways. To overcome this
limitation, we have developed a probabilistic DFT
algorithm (ConTrack) that identifies the most likely
pathways between two regions. We introduce the
algorithm in three parts: a sampler to generate a large
set of potential pathways, a scoring algorithm that
measures the likelihood of a pathway, and an
inferential step to identify the most likely pathways
connecting two regions. In a series of experiments
using human data, we show that ConTrack estimates known
pathways at positions that are consistent with those
found using a high quality deterministic algorithm.
Further we show that separating sampling and scoring
enables ConTrack to identify valid pathways, known to
exist, that are missed by other deterministic and
probabilistic DFT algorithms.},

the tracer at multiple sites in the brain of a macaque

segmented and registered the fibers (somatosensory and

the same pathways on the DTI data using a classical
diffusion tracing technique with the injection sites as
seeds. To evaluate the performance of DTI fiber
tracing, we compared the fibers derived from the DTI
tractography with those segmented from the histology.
We also studied the influence of the parameters
controlling the tractography by comparing Dice
superimposition coefficients between histology and DTI
segmentations. While there was generally good visual
agreement between the two methods, our quantitative
comparisons reveal certain limitations of DTI

We propose a new variational framework that

nature of the noise on the images leads us to a maximum

further reduce the noise, we optimally exploit the
spatial correlation by adding to the estimation an

easily optimized thanks to the use of the recently
introduced Log-Euclidean metrics. Results on real

Journal = {J Magn Reson Imaging},
Volume = {24},
Number = {5},
Pages = {1188-93},
abstract = {PURPOSE: To correct eddy-current artifacts in
diffusion tensor (DT) images without the need to obtain
auxiliary scans for the sole purpose of correction.
MATERIALS AND METHODS: DT images are susceptible to
distortions caused by eddy currents induced by large
diffusion gradients. We propose a new postacquisition
correction algorithm that does not require any
auxiliary reference scans. It also avoids the
problematic procedure of cross-correlating images with
significantly different contrasts. A linear model is
used to describe the dependence of distortion
parameters (translation, scaling, and shear) on the
diffusion gradients. The model is solved numerically to
provide an individual correction for every
diffusion-weighted (DW) image. RESULTS: The assumptions
of the linear model were successfully verified in a
series of experiments on a silicon oil phantom. The
correction obtained for this phantom was compared with
correction obtained by a previously published method.
The algorithm was then shown to markedly reduce
eddy-current distortions in DT images from human
subjects. CONCLUSION: The proposed algorithm can
accurately correct eddy-current artifacts in DT images.
Its principal advantages are that only images with
comparable signals and contrasts are cross-correlated,
and no additional scans are required.},

In this paper, white matter-specific atlases in

template, the widely used ICBM-152 was used. The atlas
contains fiber orientation maps and hand-segmented
white matter parcellation maps based on diffusion
tensor imaging (DTI). Registration accuracy by linear
and non-linear transformation was measured, and
automated template-based white matter parcellation was
tested. The results showed a high correlation between
the manual ROI-based and the automated approaches for
normal adult populations. The atlases are freely
available and believed to be a useful resource as a
target template and for automated parcellation methods.

tensor model is its limited ability to provide detailed
information about multidirectional fiber architecture

visualize clinically important tracts such as the
lateral projections of the corticospinal tract. In this
report, we present a deterministic two-tensor eXtended
Streamline Tractography (XST) technique, which
successfully traces through regions of crossing fibers.
We evaluated the method on simulated and in vivo human
brain data, comparing the results with the traditional
single-tensor and with a probabilistic tractography
technique. By tracing the corticospinal tract and
correlating with fMRI-determined motor cortex in both
healthy subjects and patients with brain tumors, we
demonstrate that two-tensor deterministic streamline
tractography can accurately identify fiber bundles
consistent with anatomy and previously not detected by
conventional single-tensor tractography. When compared
to the dense connectivity maps generated by
probabilistic tractography, the method is
computationally efficient and generates discrete
geometric pathways that are simple to visualize and
clinically useful. Detection of crossing white matter
pathways can improve neurosurgical visualization of

diffusion of water (or metabolites) in anisotropic
tissues, measured noninvasively by these {NMR} methods,
is exploited to determine fiber tract orientation and
mean particle displacements. Once $D_{\textrm{eff}}$ is
estimated from a series of {NMR} pulsed-gradient,
spin-echo experiments, a tissue's three orthotropic
axes can be determined. They coincide with the eigen-
vectors of $D_{\textrm{eff}}$, while the effective
diffusivities along these orthotropic directions are
the eigenvalues of $D_{\textrm{eff}}$. Diffusion
ellipsoids, constructed in each voxel from
$D_{\textrm{eff}}$, depict both these orthotropic axes
and the mean diffusion distances in these directions.
Moreover, the three scalar invariants of
$D_{\textrm{eff}}$, which are independent of the
tissue's orientation in the laboratory frame of
reference, reveal useful information about molecular
mobility reflective of local microstructure and
anatomy. Inherently, tensors (like $D_{\textrm{eff}}$)

Patients treated with interferon-beta (IFN-beta) have
an even more significant reduction in the percentage of

of IFN-gamma-expressing CD8 cells is increased in SPMS
patients, a group with reduced functional suppressor

that IFN-gamma secretion by CD8 T cells and functional

energy configuration of a simulated spin glass in which

is embedded into a simulated magnetic external field

fiber orientations according to diffusion models. A
model of spin interactions related to the curvature of
the underlying fascicles introduces a low bending
potential constraint. Hence, the optimal configuration
is a trade-off between these two kind of forces acting
on the spins. Experimental results are presented for
the simplest spin glass model made up of compass

density function of up to 2 intra-voxel fiber

architecture within a voxel is then assessed by
calculating the relative probabilities of a 1 and 2

signal to noise ratios, it is possible to accurately
characterize the directions of 2 intersecting fibers
using a 2 fiber model. The shortcomings of
under-fitting a 2 fiber model, or over-fitting a 1
fiber model, are explored. This new algorithm enhances
the tools available for fiber tracking.},

communicate with each other via axons for the formation
of complex neural networks. The structural mapping of
such networks during health and disease states is
essential for understanding brain function. However,
our understanding of brain structural connectivity is
surprisingly limited, due in part to the lack of
noninvasive methodologies to study axonal anatomy.
Diffusion tensor imaging (DTI) is a recently developed
MRI technique that can measure macroscopic axonal
organization in nervous system tissues. In this
article, the principles of DTI methodologies are
explained, and several applications introduced,
including visualization of axonal tracts in myelin and
axonal injuries as well as human brain and mouse
embryonic development. The strengths and limitations of
DTI and key areas for future research and development
are also discussed.},

Journal = {IEEE transactions on medical imaging},

abstract = {We propose an integral concept for tractography to
describe crossing and splitting fibre bundles based on
the fibre orientation distribution function (ODF)
estimated from high angular resolution diffusion
imaging (HARDI). We show that in order to perform
accurate probabilistic tractography, one needs to use a
fibre ODF estimation and not the diffusion ODF. We use
a new fibre ODF estimation obtained from a sharpening
deconvolution transform (SDT) of the diffusion ODF
reconstructed from q-ball imaging (QBI). This SDT
provides new insight into the relationship between the
HARDI signal, the diffusion ODF, and the fibre ODF. We
demonstrate that the SDT agrees with classical
spherical deconvolution and improves the angular
resolution of QBI. Another important contribution of
this paper is the development of new deterministic and
new probabilistic tractography algorithms using the
full multidirectional information obtained through use
of the fibre ODF. An extensive comparison study is
performed on human brain datasets comparing our new
deterministic and probabilistic tracking algorithms in
complex fibre crossing regions. Finally, as an
application of our new probabilistic tracking, we
quantify the reconstruction of transcallosal fibres
intersecting with the corona radiata and the superior
longitudinal fasciculus in a group of eight subjects.
Most current diffusion tensor imaging (DTI)-based
methods neglect these fibres, which might lead to
incorrect interpretations of brain functions.},

abstract = {A fundamental issue in neuroscience is the relation
between structure and function. However, gross
landmarks do not correspond well to microstructural
borders and cytoarchitecture cannot be visualized in a
living brain used for functional studies. Here, we used
diffusion-weighted and functional MRI to test
structure-function relations directly. Distinct
neocortical regions were defined as volumes having
similar connectivity profiles and borders identified
where connectivity changed. Without using prior
information, we found an abrupt profile change where
the border between supplementary motor area (SMA) and
pre-SMA is expected. Consistent with this anatomical
assignment, putative SMA and pre-SMA connected to motor
and prefrontal regions, respectively. Excellent spatial
correlations were found between volumes defined by
using connectivity alone and volumes activated during
tasks designed to involve SMA or pre-SMA selectively.
This finding demonstrates a strong relationship between
structure and function in medial frontal cortex and
offers a strategy for testing such correspondences
elsewhere in the brain.},

work, we construct such an atlas and use it to cluster

atlas, we start with a set of labeled ROIs specified by
an expert and extract the fiber tracts initiating from
each ROI. Affine registration is used to project the
extracted fiber tracts of each subject to the atlas,
whereas their B-spline representation is used to
efficiently compare them to the fiber tracts in the
atlas and assign cluster labels. Expert visual
inspection of the result confirms that the proposed
method is very promising and efficient in clustering of
the known bundles of fiber tracts.},

Title = {Optimal imaging parameters for fiber-orientation
estimation in diffusion MRI},
Journal = {NeuroImage},
Volume = {27},
Pages = {357 367},
abstract = {This study uses Monte Carlo simulations to investigate
the optimal value of the diffusion weighting factor b
for estimating white-matter fiber orientations using
diffusion MRI with a standard spherical sampling
scheme. We devise an algorithm for determining the
optimal echo time, pulse width, and pulse separation in
the pulsed-gradient spinecho sequence for a specific
value of b. The Monte Carlo simulations provide an
estimate of the optimal value of b for recovering one
and two fiber orientations. We show that the optimum is
largely independent of the noise level in the
measurements and the number of gradient directions and
that the optimum depends only weakly on the diffusion
anisotropy, the maximum gradient strength, and the spin
spin relaxation time. The optimum depends strongly on
the mean diffusivity. In brain tissue, the optima we
estimate are in the ranges [0.7, 1.0] \times 10^9 s
m^{-2} and [2.2, 2.8] \times 10^9 s m^{-2} for the one-
and two-fiber cases, respectively. The best b for
estimating the fractional anisotropy is slightly higher
than for estimating fiber directions in the one-fiber
case and slightly lower in the two-fiber case. To
estimate Tr(D) in the onefiber case, the optimal
setting is higher still. Simulations suggest that a
ratio of high to low b measurements of 5 to 1 is a good
compromise for measuring fiber directions and size and
shape indices.},

Number = {c},
abstract = {Based on the Fourier transform relation between
diffusion MR signals and the underlying diffusion
displacement, a new relation is derived to estimate the
spin distribution function (SDF) directly from
diffusion MR signals. This relation leads to an imaging
method called generalized q-sampling imaging (GQI),
which can obtain the SDF from the shell sampling scheme
used in q-ball imaging (QBI) or the grid sampling
scheme used in diffusion spectrum imaging (DSI). The
accuracy of GQI was evaluated by a simulation study and
an in vivo experiment in comparison with QBI and DSI.
The simulation results showed that the accuracy of GQI
was comparable to that of QBI and DSI. The simulation
study of GQI also showed that an anisotropy index,
named quantitative anisotropy, was correlated with the
volume fraction of the resolved fiber component. The in
vivo images of GQI demonstrated that SDF patterns were
similar to the ODFs reconstructed by QBI or DSI. The
tractography generated from GQI was also similar to
those generated from QBI and DSI. In conclusion, the
proposed GQI method can be applied to grid or shell
sampling schemes and can provide directional and
quantitative information about the crossing fibers.},

measurements.},
Journal = {J Magn Reson Imaging},
Volume = {25},
Number = {5},
Pages = {1051-8},
abstract = {PURPOSE: To propose a new method to optimize the
ordering of gradient directions in diffusion-weighted
MRI so that partial scans have the best spherical
coverage. MATERIALS AND METHODS: Diffusion-weighted MRI
often uses a spherical sampling scheme, which acquires
images sequentially with diffusion-weighting gradients
in unique directions distributed isotropically on the
hemisphere. If not all of the measurements can be
completed, the quality of diffusion tensors fitted to
the partial scan is sensitive to the order of the
gradient directions in the scanner protocol. If the
directions are in a random order, then a partial scan
may cover some parts of the hemisphere densely but
other parts sparsely and thus provide poor spherical
coverage. We compare the results of ordering with
previously published methods for optimizing the
acquisition in simulation. RESULTS: Results show that
all methods produce similar results and all improve the
accuracy of the estimated diffusion tensors
significantly over unordered acquisitions. CONCLUSION:
The new ordering method improves the spherical coverage
of partial scans and has the advantage of maintaining
the optimal coverage of the complete scan.},

Pages = {832--44},
abstract = {We introduce an automatic method that we call
tract-based morphometry, or TBM, for measurement and
analysis of diffusion MRI data along white matter fiber
tracts. Using subject-specific tractography bundle
segmentations, we generate an arc length
parameterization of the bundle with point
correspondences across all fibers and all subjects,
allowing tract-based measurement and analysis. In this
paper we present a quantitative comparison of fiber
coordinate systems from the literature and we introduce
an improved optimal match method that reduces spatial
distortion and improves intra- and inter-subject
variability of FA measurements. We propose a method for
generating arc length correspondences across
hemispheres, enabling a TBM study of interhemispheric
diffusion asymmetries in the arcuate fasciculus (AF)
and cingulum bundle (CB). The results of this study
demonstrate that TBM can detect differences that may
not be found by measuring means of scalar invariants in
entire tracts, such as the mean diffusivity (MD)
differences found in AF. We report TBM results of
higher fractional anisotropy (FA) in the left
hemisphere in AF (caused primarily by lower lambda(3),
the smallest eigenvalue of the diffusion tensor, in the
left AF), and higher left hemisphere FA in CB (related
to higher lambda(1), the largest eigenvalue of the
diffusion tensor, in the left CB). By mapping the
significance levels onto the tractography trajectories
for each structure, we demonstrate the anatomical
locations of the interhemispheric differences. The TBM
approach brings analysis of DTI data into the
clinically and neuroanatomically relevant framework of
the tract anatomy.},

abstract = {We propose a regularized, fast, and robust analytical
solution for the Q-ball imaging (QBI) reconstruction of
the orientation distribution function (ODF) together
with its detailed validation and a discussion on its
benefits over the state-of-the-art. Our analytical
solution is achieved by modeling the raw high angular
resolution diffusion imaging signal with a spherical
harmonic basis that incorporates a regularization term
based on the Laplace Beltrami operator defined on the
unit sphere. This leads to an elegant mathematical
simplification of the FunkRadon transform which
approximates the ODF. We prove a new corollary of the
FunkHecke theorem to obtain this simplification. Then,
we show that the LaplaceBeltrami regularization is
theoretically and practically better than Tikhonov
regularization. At the cost of slightly reducing
angular resolution, the LaplaceBeltrami regularization
reduces ODF estimation errors and improves fiber
detection while reducing angular error in the ODF
maxima detected. Finally, a careful quantitative
validation is performed against ground truth from
synthetic data and against real data from a biological
phantom and a human brain dataset. We show that our
technique is also able to recover known fiber crossings
in the human brain and provides the practical advantage
of being up to 15 times faster than original numerical

abstract = {Diffusion weighted imaging ({DWI}) techniques have
been used to study human brain white matter fiber
structures in vivo. Commonly used standard diffusion
tensor magnetic resonance imaging ({DTI}) tractography
derived from the second order diffusion tensor model
has limitations in its ability to resolve complex fiber
tracts. We propose a new fiber tracking method based on
the generalized diffusion tensor ({GDT}) model. This
new method better models the anisotropic diffusion
process in human brain by using the generalized
diffusion simulation-based fiber tractography ({GDST}).
Due to the additional information provided by {GDT},
the {GDST} method simulates the underlying physical
diffusion process of the human brain more accurately
than does the standard {DTI} method. The effectiveness
of the new fiber tracking algorithm was demonstrated
via analyses on real and synthetic {DWI} datasets. In
addition, the general analytic expression of high order
b matrix is derived in the case of twice refocused
spin-echo ({TRSE}) pulse sequence which is used in the
{DWI} data acquisition. Based on our results, we
discuss the benefits of {GDT} and the second order

no cost in scanning efficiency or effectiveness, and
allows more flexible diffusion gradient timing. By
adjusting the timing of the diffusion gradients, eddy

be nulled, and eddy currents with similar decay
constants can be greatly reduced. This new sequence is
demonstrated in phantom measurements and in diffusion
anisotropy images of normal human brain.},

Journal = {IEEE Trans Med Imaging},
Volume = {21},

Pages = {525-37},
abstract = {We describe a method for automatically building
statistical shape models from a training set of example
boundaries/surfaces. These models show considerable
promise as a basis for segmenting and interpreting
images. One of the drawbacks of the approach is,
however, the need to establish a set of dense
correspondences between all members of a set of
training shapes. Often this is achieved by locating a
set of "landmarks" manually on each training image,
which is time consuming and subjective in two
dimensions and almost impossible in three dimensions.
We describe how shape models can be built automatically
by posing the correspondence problem as one of finding
the parameterization for each shape in the training
set. We select the set of parameterizations that build
the "best" model. We define "best" as that which
minimizes the description length of the training set,
arguing that this leads to models with good
compactness, specificity and generalization ability. We
show how a set of shape parameterizations can be
represented and manipulated in order to build a minimum
description length model. Results are given for several
different training sets of two-dimensional boundaries,
showing that the proposed method constructs better
models than other approaches including manual
landmarking-the current gold standard. We also show
that the method can be extended straightforwardly to
three dimensions.},

abstract = {This study has investigated the relationship between
the noise sensitivity of measurement by magnetic
resonance imaging (MRI) of the diffusion tensor (D) of
water and the number N of diffusion-weighting (DW)
gradient directions, using computer simulations of
strongly anisotropic fibers with variable orientation.
The DW directions uniformly sampled the diffusion
ellipsoid surface. It is shown that the variation of
the signal-to-noise ratio (SNR) of three ideally
rotationally invariant scalars of D due to variable
fiber orientation provides an objective quantitative
measure for the diffusion ellipsoid sampling
efficiency, which is independent of the SNR value of
the baseline signal obtained without DW; the SNR
variation decreased asymptotically with increasing N.
The minimum number N(0) of DW directions, which
minimized the SNR variation of the three scalars of D
was determined, thereby achieving the most efficient
ellipsoid sampling. The resulting time efficient
diffusion tensor imaging (DTI) protocols provide robust
estimation of diffusion anisotropy in the presence of
noise and can improve the repeatability/reliability of
DTI experiments when there is high variability in the
orientation of similar anisotropic structures, as for
example, in studies which require repeated measurement
of one individual, intersubject comparisons or

Pages = {S139-S146},
abstract = {When applying pulsed field gradient (PFG) NMR
experiments to determine the molecular mobility
characterized by the diffusion coefficient, it is
crucial to have control over all experimental
parameters that may affect the performance of the
diffusion experiment. This could be diffusion
measurement in the presence of magnetic field
transients, internal magnetic field gradients, either
constant or spatially varying, convection, mechanical
vibrations, or in the presence of physical restrictions
affecting the diffusion propagator. The effect of these
parameters on the diffusion experiment is discussed and
visualized. It is also outlined how to minimize their
influence on the measured diffusivity that is extracted
from the PFG-NMR experiment. For an expanded and more
general treatment we refer to the excellent reviews by
Dr William S. Price (Concepts Magn. Reson. 1997; 9:
299; 1998; 10: 197) and the references therein.},

anisotropy of individual fibre populations. The PDFs
are incorporated in a probabilistic fibre-tracking
method to allow the estimation of whole-brain maps of
anatomical connection probability. These methods are
applied in two exemplar experiments in the
corticospinal tract to show that it is possible to
connect the entire primary motor cortex (M1) when
tracing from the cerebral peduncles, and that the
reverse experiment of tracking from M1 successfully
identifies high probability connection via the
pyramidal tracts. Using the extracted PAS in
probabilistic fibre tracking allows higher specificity
and sensitivity than previously reported fibre tracking
using diffusion-weighted MRI in the corticospinal

a powerful method to extract the anatomical

the currently available methods of fibre tracking is
the reconstruction of long neuronal pathways in small
successive steps by following the local, voxel-defined
fibre direction. Starting from local information on the
diffusivity, long-distance connections are determined.
This method is inherently prone to instability, since a
mistake at a single crossing affects radically the
final result. In this paper we present a method based
on a new principle. Instead of walking successively
through the volume all neuronal pathways and the
totality of the signal is taken into account at the
same time. This novel approach is capable to
reconstruct crossing and spreading fibre configuration.},

abstract = {Anisotropic water diffusion in neural fibres such as
nerve, white matter in spinal cord, or white matter in

tensor imaging (DTI) to track fibre pathways. The fact
that water diffusion is sensitive to the underlying
tissue microstructure provides a unique method of
assessing the orientation and integrity of these neural
fibres, which may be useful in assessing a number of
neurological disorders. The purpose of this review is
to characterize the relationship of nuclear magnetic
resonance measurements of water diffusion and its
anisotropy (i.e. directional dependence) with the
underlying microstructure of neural fibres. The
emphasis of the review will be on model neurological
systems both in vitro and in vivo. A systematic
discussion of the possible sources of anisotropy and
their evaluation will be presented followed by an
overview of various studies of restricted diffusion and
compartmentation as they relate to anisotropy.
Pertinent pathological models, developmental studies
and theoretical analyses provide further insight into
the basis of anisotropic diffusion and its potential
utility in the nervous system.},

Volume = {29},
Number = {1},
Pages = {132--45},
abstract = {In this paper, we present a robust approach to the
registration of white matter tractographies extracted
from diffusion tensor-magnetic resonance imaging scans.
The fibers are projected into a high dimensional
feature space based on the sequence of their 3-D
coordinates. Adaptive mean-shift clustering is applied
to extract a compact set of representative fiber-modes
(FM). Each FM is assigned to a multivariate Gaussian
distribution according to its population thereby
leading to a Gaussian mixture model (GMM)
representation for the entire set of fibers. The
registration between two fiber sets is treated as the
alignment of two GMMs and is performed by maximizing
their correlation ratio. A nine-parameters affine
transform is recovered and eventually refined to a
twelve-parameters affine transform using an innovative
mean-shift based registration refinement scheme
presented in this paper. The validation of the
algorithm on synthetic intrasubject data demonstrates
its robustness to interrupted and deviating fiber
artifacts as well as outliers. Using real intrasubject
data, a comparison is conducted to other intensity
based and fiber-based registration algorithms,
demonstrating competitive results. An option for
tracking-in-time, on specific white matter fiber
tracts, is also demonstrated on the real data.},

Title = {Brain Anatomical Structure Segmentation by Hybrid
Discriminative/Generative Models},
Journal = {Transactions on Medical Imaging},
Volume = {in press},
abstract = {In this paper, a hybrid discriminative/generative
model for brain anatomical structure segmentation is
proposed. The learning aspect of the approach is
emphasized. In the discriminative appearance models,
various cues such as intensity and curvatures are
combined to locally capture the complex appearances of
different anatomical structures. A probabilistic
boosting tree (PBT) framework is adopted to learn
multi-class discriminative models that combine hundreds
of features across different scales. On the generative
side, Principal Component Analysis (PCA) shape models
are used to capture the global shape information about
each anatomical structure. The parameters to combine
the discriminative appearance and generative shape
models are also automatically learned. Thus low-level
and highlevel information is learned and integrated in
a hybrid model. Segmentations are obtained by
minimizing an energy function associated with the
proposed hybrid model. Finally, a gridface structure is
designed to explicitly represent the 3D region
topology. This representation handles an arbitrary
number of regions and facilitates fast surface
evolution. Our system was trained and tested on a set
of 3D MRI volumes and the results obtained are
encouraging.},

abstract = {The brain activity during perception or cognition is
mostly examined by functional magnetic resonance
imaging (fMRI). However, the cause of the detected

magnetic resonance imaging (DTMRI) as a noninvasive
modality providing in vivo anatomical information
allows determining neural fiber connections which leads
to brain mapping. Still a complete map of fiber paths
representing the human brain is missing in literature.
One of the main drawbacks of reliable fiber mapping is
the correct detection of the orientation of multiple
fibers within a single imaging voxel. In this study a
method based on linear data structures is proposed to
define the fiber paths regarding their diffusivity.
Another advantage of the proposed method is that the
analysis is applied on entire brain diffusion tensor
data. The implementation results are promising, so that
the method will be developed as a rapid fiber
tractography algorithm for the clinical use as future
study.},

this paper presents how brain connectivity could be
modelled globally by means of a random walk algorithm.
The mass of connections thus generated was then
virtually dissected to uncover different tracts.
Corticospinal, corticobulbar, and corticothalamic
tracts, the corpus callosum, the limbic system, several
cortical association bundles, the cerebellar peduncles,
and the medial lemniscus were all investigated. The
results were then displayed in the form of an in vivo

the individual fibre tracts were then compared to known

Title = {Eddy current correction in diffusion-weighted imaging
using pairs of images acquired with opposite diffusion
gradient polarity.},
Journal = {Magn Reson Med},
Volume = {51},
Number = {1},
Pages = {188-93},
abstract = {In echo-planar-based diffusion-weighted imaging (DWI)
and diffusion tensor imaging (DTI), the evaluation of
diffusion parameters such as apparent diffusion
coefficients and anisotropy indices is affected by
image distortions that arise from residual eddy
currents produced by the diffusion-sensitizing
gradients. Correction methods that coregister
diffusion-weighted and non-diffusion-weighted images
suffer from the different contrast properties inherent
in these image types. Here, a postprocessing correction
scheme is introduced that makes use of the inverse
characteristics of distortions generated by gradients
with reversed polarity. In this approach, only
diffusion-weighted images with identical contrast are
included for correction. That is,
non-diffusion-weighted images are not needed as a
reference for registration. Furthermore, the
acquisition of an additional dataset with moderate
diffusion-weighting as suggested by Haselgrove and
Moore (Magn Reson Med 1996;36:960-964) is not required.
With phantom data it is shown that the theoretically
expected symmetry of distortions is preserved in the
images to a very high degree, demonstrating the
practicality of the new method. Results from human
brain images are also presented.},

Journal = {Radiology},
Volume = {229},
Number = {3},
Pages = {673--81},
abstract = {PURPOSE: To evaluate the normal brains of adults and
neonates for regional and age-related differences in
apparent diffusion coefficient (ADC) and fractional
anisotropy (FA). MATERIALS AND METHODS: Eight healthy
adults and 20 healthy neonates were examined with a
3.0-T head-only magnetic resonance (MR) imaging unit by
using a single-shot diffusion-tensor sequence. Trace
ADC maps, FA maps, directional maps of the putative
directions of white matter (WM) tracts, and
fiber-tracking maps were obtained. Regions of
interest-eight in WM and one in gray matter (GM)-were
predefined for the ADC and FA measurements. The Student
t test was used to compare FA and ADC between adults
and neonates, whereas the Tukey multiple-comparison
test was used to compare FA and ADC in different brain
regions in the adult and neonate groups. RESULTS: A
global elevation in ADC (P <.001) in both GM and WM and
a reduction in FA (P <.001) in WM were observed in
neonates as compared with these values in adults. In
addition, significant regional variations in FA and ADC
were observed in both groups. Regional variations in FA
and ADC were less remarkable in adults, whereas
neonates had consistently higher FA values and lower
ADC values in the central WM as compared with these
values in the peripheral WM. Fiber tracking revealed
only major WM tracts in the neonates but fibers
extending to the peripheral WM in the adults.
CONCLUSION: There were regional differences in FA and
ADC values in the neonates; such variations were less
remarkable in the adults.},

subregions whose locations correspond to nuclei
described previously in histological studies. The
connections that we found between thalamus and cortex
were similar to those reported for non-human primates
and were reproducible between individuals. Our results
provide the first quantitative demonstration of
reliable inference of anatomical connectivity between
human gray matter structures using diffusion data and
the first connectivity-based segmentation of gray

Journal = {Magnetic Resonance in Medicine},
Volume = {42},
Number = {3},
abstract = {This paper investigates the use of color to represent
the directional information contained in the diffusion
tensor. Ideally, one wants to take into account both
the properties of human color vision and of the given
display hardware to produce a representation in which
differences in the orientation of anisotropic
structures are proportional to the perceived
differences in color. It is argued here that such a
goal cannot be achieved in general and therefore,
empirical or heuristic schemes, which avoid some of the
common artifacts of previously proposed approaches, are
implemented. Directionally encoded color (DEC) maps of
the human brain obtained using these schemes clearly
show the main association, projection, and commissural
white matter pathways. In the brainstem, motor and
sensory pathways are easily identified and can be
differentiated from the transverse pontine fibers and
the cerebellar peduncles. DEC maps obtained from
diffusion tensor imaging data provide a simple and
effective way to visualize fiber direction, useful for
investigating the structural anatomy of different
organs. Magn Reson Med 42:526-540, 1999. © 1999

Pages = {530-8},

(DWI) as a method for examining neural connectivity,
its accuracy has not been formally evaluated. In this
study, we directly compared connections that were
visualized using injected neural tract tracers
(WGA-HRP) with those obtained using in-vivo diffusion
tensor imaging (DTI) tractography. First, we injected
the tracer at multiple sites in the brain of a macaque
monkey; second, we reconstructed the histological
sections of the labeled fiber tracts in 3D; third, we
segmented and registered the fibers (somatosensory and
motor tracts) with the anatomical in-vivo MRI from the
same animal; and last, we conducted fiber tracing along
the same pathways on the DTI data using a classical
diffusion tracing technique with the injection sites as
seeds. To evaluate the performance of DTI fiber
tracing, we compared the fibers derived from the DTI
tractography with those segmented from the histology.
We also studied the influence of the parameters
controlling the tractography by comparing Dice
superimposition coefficients between histology and DTI
segmentations. While there was generally good visual
agreement between the two methods, our quantitative
comparisons reveal certain limitations of DTI
tractography, particularly for regions at remote
locations from seeds. We have thus demonstrated the
importance of appropriate settings for realistic
tractography results.},

tracts.}},
Journal = {IEEE transactions on medical imaging},
Volume = {26},
Number = {11},
Pages = {1547--54},
abstract = {We present a new five-dimensional (5-D) space
representation of diffusion magnetic resonance imaging
(dMRI) of high angular resolution. This 5-D space is
basically a non-Euclidean space of position and
orientation in which crossing fiber tracts can be
clearly disentangled, that cannot be separated in
three-dimensional position space. This new
representation provides many possibilities for
processing and analysis since classical methods for
scalar images can be extended to higher dimensions even
if the spaces are not Euclidean. In this paper, we show
examples of how regularization and segmentation of dMRI
is simplified with this new representation. The
regularization is used with the purpose of denoising
and but also to facilitate the segmentation task by
using several scales, each scale representing a
different level of resolution. We implement in five
dimensions the Chan-Vese method combined with active
contours without edges for the segmentation and the
total variation functional for the regularization. The
purpose of this paper is to explore the possibility of
segmenting white matter structures directly as entirely
separated bundles in this 5-D space. We will present
results from a synthetic model and results on real data
of a human brain acquired with diffusion spectrum
magnetic resonance imaging (MRI), one of the dMRI of
high angular resolution available. These results will
lead us to the conclusion that this new
high-dimensional representation indeed simplifies the
problem of segmentation and regularization.},

Title = {A bayesian framework to identify principal intravoxel
diffusion profiles based on diffusion-weighted
\{{M}{R}\} imaging},
Journal = {NeuroImage},
Volume = {42},
Number = {2},
Pages = {750-770},
abstract = {In this paper we introduce a new method to
characterize the intravoxel anisotropy based on
diffusion-weighted imaging (DWI). The proposed
solution, under a fully Bayesian formalism, deals with
the problem of joint Bayesian Model selection and
parameter estimation to reconstruct the principal
diffusion profiles or primary fiber orientations in a
voxel. We develop an efficient stochastic algorithm
based on the reversible jump Markov chain Monte Carlo
(RJMCMC) method in order to perform the Bayesian
computation. RJMCMC is a good choice for this problem
because of its ability to jump between models of
different dimensionality. This methodology provides
posterior estimates of the parameters of interest
(fiber orientation, diffusivities etc) unconditional of
the model assumed. It also gives an empirical posterior
distribution of the number of primary nerve fiber
orientations given the DWI data. Different probability
maps can be assessed using this methodology: 1) the
intravoxel fiber orientation map (or orientational
distribution function) that gives the probability of
finding a fiber in a particular spatial orientation; 2)
a three-dimensional map of the probability of finding a
particular number of fibers in each voxel; 3) a
three-dimensional MaxPro (maximum probability) map that
provides the most probable number of fibers for each
voxel. In order to study the performance and
reliability of the presented approach, we tested it on
synthetic data; an ex-vivo phantom of intersecting
capillaries; and DWI data from a human subject.},

Also, damage to portions of these tracts is associated

measurements, occipital-callosal projections were
estimated from each subject's left and right

converged onto the same positions within the splenium.
We further characterized the properties of the
estimated occipital-callosal fiber tracts by combining
them with functional MRI. We used functional MRI to
identify visual field maps in cortex and labeled fibers
by the cortical functional response at the fiber
endpoint. This labeling reveals a regular organization
of the fibers within the splenium. The dorsal visual
maps (dorsal V3, V3A, V3B, V7) send projections through
a large band in the middle of the splenium, whereas
ventral visual maps (ventral V3, V4) send projections
through the inferior-anterior corner of the splenium.
The agreement between the independent left/right
estimates, further supported by previous descriptions
of homologous tracts in macaque, validates the DTI-FT
methods. However, a principal limitation of these
methods is low sensitivity: a large number of fiber
tracts that connect homotopic regions of ventral and
lateral visual cortex were undetected. We conclude that
most of the estimated tracts are real and can be
localized with a precision of 1-2 mm, but many tracts
are missed because of data and algorithm limitations.},

able to interactively delineate and visualize white

dorsal (PMd) and ventral (PMv) parts, which have
distinct cytoarchitecture, function, and patterns of

areas. The borders of their subregions are less well
defined in the human brain. Here we use diffusion
tractography to identify a reproducible border between
dorsal and ventral subregions of human precentral
gyrus. We derive connectivity fingerprints for the two
subregions and demonstrate that each has a distinctive
pattern of connectivity with frontal cortex and lateral
parietal cortex, suggesting that these areas correspond
to human PMd and PMv. Although putative human PMd has a
high probability of connection with the superior
parietal lobule, dorsal prefrontal cortex, and
cingulate cortex, human PMv has a higher probability of
connection with the anterior inferior parietal lobule
and ventral prefrontal cortex. Finally, we assess the
correspondence between our PMd/PMv border and local
sulcal and functional anatomy. The location of the
border falls at the level of the gyral branch that
divides the inferior precentral sulcus from the
superior precentral sulcus and corresponded closely to
the location of a functional border defined using
previous functional magnetic resonance imaging studies.},

Pages = {164-176},
abstract = {Diffusion MRI is a non-invasive imaging technique that
allows the measurement of water molecule diffusion
through tissue in vivo. The directional features of
water diffusion allow one to infer the connectivity
patterns prevalent in tissue and possibly track changes
in this connectivity over time for various clinical
applications. In this paper, we present a novel
statistical model for diffusion-weighted MR signal
attenuation which postulates that the water molecule
diffusion can be characterized by a continuous mixture
of diffusion tensors. An interesting observation is
that this continuous mixture and the MR signal
attenuation are related through the Laplace transform
of a probability distribution over symmetric positive
definite matrices. We then show that when the mixing
distribution is a Wishart distribution, the resulting
closed form of the Laplace transform leads to a
Rigaut-type asymptotic fractal expression, which has
been phenomenologically used in the past to explain the
MR signal decay but never with a rigorous mathematical
justification until now. Our model not only includes
the traditional diffusion tensor model as a special
instance in the limiting case, but also can be adjusted
to describe complex tissue structure involving multiple
fiber populations. Using this new model in conjunction
with a spherical deconvolution approach, we present an
efficient scheme for estimating the water molecule
displacement probability functions on a voxel-by-voxel
basis. Experimental results on both simulations and
real data are presented to demonstrate the robustness
and accuracy of the proposed algorithms.},

Journal = {NeuroImage},
Volume = {30},
Number = {1},
Pages = {121--9},
abstract = {Diffusion tensor imaging (DTI) has seen increased
usage in clinical and basic science research in the
past decade. By assessing the water diffusion
anisotropy within biological tissues, e.g. brain,
researchers can infer different fiber structures
important for neural pathways. A typical DTI data set
contains at least one base image and six
diffusion-weighted images along non-collinear encoding
directions. The resultant images can then be combined
to derive the three principal axes of the diffusion
tensor and their respective cross terms, which can in
turn be used to compute fractional anisotropy (FA)
maps, apparent diffusion coefficient (ADC) maps, and to
construct axonal fibers. The above operations all
assume that DTI images along different
diffusion-weighting directions for the same brain
register to each other without spatial distortions.
This assumption is generally false, as the large
diffusion-weighting gradients would usually induce eddy
currents to generate diffusion-weighting
direction-dependent field gradients, leading to
mis-registration within the DTI data set. Traditional
methods for correcting magnetic field-induced
distortions do not usually take into account these
direction-dependent eddy currents unique for DTI, and
they are usually time-consuming because multiple phase
images need to be acquired. In this report, we describe
our theory and implementation of an efficient and
effective method to correct for the main field and eddy
current-induced direction-dependent distortions for DTI
images under a unified framework to facilitate the
daily practice of DTI acquisitions.},

the major imaging modality to study properties of white
matter and the geometry of fiber tracts of the human

statistics of fractional anisotropy (FA) and mean
diffusivity (MD) derived from tensors. Existing
analysis techniques do not sufficiently take into
account that the measurements are tensors, and thus
require proper interpolation and statistics of tensors,
and that regions of interest are fiber tracts with
complex spatial geometry. We propose a new framework
for quantitative tract-oriented DTI analysis that
systematically includes tensor interpolation and
averaging, using nonlinear Riemannian symmetric space.
A new measure of tensor anisotropy, called geodesic
anisotropy (GA) is applied and compared with FA. As a
result, tracts of interest are represented by the
geometry of the medial spine attributed with tensor
statistics (average and variance) calculated within
cross-sections. Feasibility of our approach is
demonstrated on various fiber tracts of a single data
set. A validation study, based on six repeated scans of
the same subject, assesses the reproducibility of this
new DTI data analysis framework.},
