Diffusion tensor imaging tractography is commonly used to quantify white matter tracts in the
human brain via parameters such as fractional anisotropy and mean diffusivity. Simulation …

In this article, we highlight an issue that arises when using multiple b‐values in a model‐
based analysis of diffusion MR data for tractography. The non‐monoexponential decay …

Diffusion tractography offers enormous potential for the study of human brain anatomy.
However, as a method to study brain connectivity, tractography suffers from limitations, as it …

Diffusion MRI streamlines tractography suffers from a number of inherent limitations, one of
which is the accurate determination of when streamlines should be terminated. Use of an …

Mapping complex crossing fibers using diffusion MRI techniques requires adequate angular
precision and accuracy. Beyond diffusion tensor imaging (DTI), high angular resolution …

Purpose To identify optimal pulsed gradient spin‐echo (PGSE) and oscillating gradient spin‐
echo (OGSE) sequence settings for maximizing sensitivity to axon diameter in idealized and …

Recent advances in diffusion MRI tractography permit the generation of dense weighted
structural connectomes that offer greater insight into brain organization. However, these …

Diffusion MRI allows the structural connectivity of the whole brain (the 'tractogram') to be
estimated in vivo non-invasively using streamline tractography. The biological accuracy of …

Diffusion MRI (dMRI) is a unique tool for the study of brain circuitry, as it allows us to image
both the macroscopic trajectories and the microstructural properties of axon bundles in vivo …

The bootstrap technique is an extremely powerful nonparametric statistical procedure for
determining the uncertainty in a given statistic. However, its use in diffusion tensor MRI …
