BACKGROUND AND PURPOSE: In human brain, the relationship between MR signal and b
value is complicated by cerebral perfusion, restricted diffusion, anisotropy, cellular …

The objectives were to study the “impact” of the magnetic field strength on diffusion tensor
imaging (DTI) metrics and also to determine whether magnetic-field-related differences in T2 …

Diffusion-weighted MRI images acquired at b-value greater than 1000smm− 2 measure the
diffusion of a restricted pool of water molecules. High b-value images are accompanied by a …

Diffusion-weighted magnetic resonance imaging (MRI) provides information about tissue
water diffusion. Diffusion anisotropy, which can be measured with diffusion tensor MRI, is a …

Recent studies have shown that the diffusional signal decay in human brain is non‐
monoexponential and may be described in terms of compartmentalized water fractions …

The diffusion tensor is currently the accepted model of diffusion in biological tissues. The
measured diffusion behavior may be more complex when two or more distinct tissues with …

A review of the behavior of different diffusion anisotropy indices (DAIs) to changes in
diffusion anisotropy was undertaken and the limitations of several previously proposed DAIs …

PURPOSE: To obtain normative human cerebral data and evaluate the anatomtomic
information in quantitative diffusion anisotropy magnetic resonance (MR) imaging …

The diffusion time dependence of the brain water diffusion tensor provides information
regarding diffusion restriction and hindrance but has received little attention, primarily due to …
