MRI Tractography of Corticospinal Tract and Arcuate Fasciculus in High-Grade Gliomas Performed by Constrained Spherical Deconvolution: Qualitative and Quantitative Analysis

, 2015
MR imaging tractography is increasingly used to perform noninvasive presurgical planning for brain gliomas. Recently, constrained spherical deconvolution tractography was shown to overcome several limitations of commonly used DTI tractography.

Connectivity matrix from a fODF weighted graph: An alternative to probabilistic tractography

, 2022
We introduce a computationally efficient fODF-weighted graph structure where shortest-paths through white matter compute the probability of connection while naturally limiting the angle of propagation between steps.

Comparing Corticocortical Interconnection Information from Tracer Studies and Probabilistic Tractography in the Postmortem Macaque Brain

, 2008
We present a study attempting to validate the corticocortical connection information obtainable from diffusion-weighted MR data. We have implemented probabilistic tractography in data acquired in a macaque model and compared this with connection ...

A thousand ways to tailor your tractography-based connectome

Did you know that there are thousands of ways to build a connectome from diffusion MRI tractography, and the choice of approach can hugely impact the final connectome and results?

Individual differences in white matter microstructure reflect variation in functional connectivity during action choice. [PDF]

, 2007
The relation between brain structure and function is of fundamental importance in neuroscience. Comparisons between behavioral and brain imaging measures suggest that variation in brain structure correlates with the presence of specific skills[1-3 ...

Somatotopic organization of motor pathways in the internal capsule: a probabilistic diffusion tractography study [PDF]

, 2012
BACKGROUND AND PURPOSE: The location of the motor pathways in the PLIC remains controversial. In the current study, we trace the fibers from the tongue, face, hand, and foot motor cortices by using probabilistic diffusion tractography and define their ...
