Tractography in Curvilinear Coordinates [PDF]
Frontiers in Neuroscience, 2021 Coordinate invariance of physical laws is central in physics, it grants us the freedom to express observations in coordinate systems that provide computational convenience. In the context of medical imaging there are numerous examples where departing from Cartesian to curvilinear coordinates leads to ease of visualization and simplicity, such as ...

Filtered Multitensor Tractography [PDF]
IEEE Transactions on Medical Imaging, 2010 We describe a technique that uses tractography to drive the local fiber model estimation. Existing techniques use independent estimation at each voxel so there is no running knowledge of confidence in the estimated model fit. We formulate fiber tracking as recursive estimation: at each step of tracing the fiber, the current estimate is guided by those ...

Tractography for an arteriovenous malformation [PDF]
Neurology, 2004 A 28-year-old woman presented with focal motor seizure involving the right upper extremity, which was well controlled with an antiepileptic agent. MRI demonstrated an arteriovenous malformation. This lesion depicted on MR angiography (figure, A) appeared to involve the sensorimotor cortices on transaxial T2-weighted MR images (figure, B; central sulcus

Hierarchical Microstructure Informed Tractography [PDF]
Brain Connectivity, 2021 Background: Tractography uses diffusion magnetic resonance imaging to noninvasively infer the macroscopic pathways of white matter fibers and it is the only available technique to probe in vivo the structural connectivity of the brain. However, despite this unique and compelling ability and its wide range of possible neurological applications ...

Diffusion MRI and anatomic tracing in the same brain reveal common failure modes of tractography
NeuroImage, 2021 Anatomic tracing is recognized as a critical source of knowledge on brain circuitry that can be used to assess the accuracy of diffusion MRI (dMRI) tractography.

Optic radiation fiber tractography in glioma patients based on high angular resolution diffusion imaging with compressed sensing compared with diffusion tensor imaging - initial experience. [PDF]
PLoS ONE, 2013 OBJECTIVE: Up to now, fiber tractography in the clinical routine is mostly based on diffusion tensor imaging (DTI). However, there are known drawbacks in the resolution of crossing or kissing fibers and in the vicinity of a tumor or edema.
