… and the diffusion weighting is given by B m , in which the scalar variable b m is solely a …
values of DWI m are the same. The more anisotropic the tensor, the more the DWI m s will vary …

… m (left two panels) and 300 mT/m (right panel). Differences in rise times for Gmax = 80 and
300 mT/m … lower δ values are achievable with Gmax = 80 mT/m (eg δ= 5 ms as shown in the …

This article presents the potential problems arising from the use of “axial” and “radial” diffusivities,
derived from the eigenvalues of the diffusion tensor, and their interpretation in terms of …

Objective: To investigate the extent and the nature of white matter tissue damage of patients
with Alzheimer's disease using diffusion tensor magnetic resonance imaging (DT-MRI). …

Objectives: To quantify, using diffusion tensor imaging (DTI), the tissue damage in lesions
and normal-appearing white matter (NAWM) from a large cohort of patients with MS and to …

Voxel-based morphometry (VBM) has been used to analyze diffusion tensor MRI (DT-MRI)
data in a number of studies. In VBM, following spatial normalization, data are smoothed to …

Diffusion-weighted (DW) magnetic resonance imaging (MRI) is the only technique that
permits a non-invasive in vivo assessment of water molecular diffusion, which reflects tissue …

Objective: Neuroimaging studies show structural alterations of various brain regions in children
and adults with attention deficit hyperactivity disorder (ADHD), although nonreplications …

OBJECTIVE To assess the feasibility of a new technique based on diffusion anisotropy to
segment white and grey matter of the brain. To use this technique to measure the mean …

… where M is the measured signal intensity, M 0 is the T2-weighted signal intensity, b ij are
the elements of the b matrix and D ij are the elements of the diffusion tensor matrix. The tensor …
