The purpose of this paper is to review the basic principles of diffusion measurement with
spin echoes. These principles can be combined with those of MR imaging to generate maps …

NMR measurements of anisotropic diffusion were studied using a three‐dimensional
random‐walk model. It was found that the apparent diffusion coefficient can be expressed in …

Publisher Summary There is a tremendous increase in the use of both magnetic (B 0), and to
a lesser extent, radiofrequency (rf or B 1) field gradients in nuclear magnetic resonance …

Radiofrequency hyperthermia of deep‐seated pelvic tumors requires noninvasive
monitoring of temperature distributions in patients. Methods of MR thermography were …

This work describes the basics of diffusion measurement in biological systems. The first
portion is dedicated to providing an understandable, classical‐mechanical description of the …

Objective To test the hypothesis that magnetic resonance imaging (MRI) results correlate
with the biochemical composition of cartilage matrix and can therefore be used to evaluate …

A novel way for calculating the diffusion-weighted nuclear magnetic resonance (NMR)
attenuation signal expression in the presence of a background gradient is developed. This …

Diffusion-weighted (DW) MRI is a powerful modality for studying microstructure in normal
and pathological tissues. The accuracy derived from DW MRI depends on the acquisition of …

Methanol diffusion in two polymer electrolyte membranes, Nafion 117 and BPSH 40 (a 40%
disulfonated wholly aromatic polyarylene ether sulfone), was measured using a modified …

A principle for self-diffusion pulse-sequence design which cancels harmful cross terms
involving both imaging and sample susceptibility-induced gradients by using antisymmetric …
