Anisotropy in diffusion‐weighted MRI

Magnetic Resonance in Medicine, 1991
AbstractDiffusional anisotropy of water protons, induced by nonrandom, directional barriers which hinder or retard water motion, is measurable by MRI. Faster water diffusion was observed when the diffusion‐sensitizing gradient direction paralleled the long axes of white matter tracts, indicative of fewer bamers to water motion.

Diffusion‐weighted MRI of fatty liver

Journal of Magnetic Resonance Imaging, 2011
AbstractPurpose:To investigate the effect of fat infiltration on the apparent diffusion coefficient (ADC) of liver, and assess the relationship between ADC and hepatic fat fraction (HFF).Materials and Methods:MRI scans of 120 consecutive patients were included in this retrospective study. Of these, 42 patients were included in the fatty liver group and

Diffusion-Weighted MRI

2003
Although conventional T2-weighted magnetic resonance imaging (MRI) is sensitive for the detection of multiple sclerosis (MS) lesions, it is not without important limitations. First, MRI lacks specificity with regard to the heterogeneous pathological substrates of individual lesions, and in consequence does not allow tissue damage to be quantified ...
