Diffusion-Weighted Magnetic Resonance Imaging [PDF]
, 2018 Magnetic resonance imaging (MRI) is a technique based on the contents and relaxation features of water in tissues. In basic MRI sequences, diffusion phenomenon of water molecules is not taken into account although it has a notable influence in the relaxation times, and therefore in the signal intensity of images.

Diffusion-Weighted Magnetic Resonance Imaging in Brain Death [PDF]
Stroke, 2000 Background —Traditionally the diagnosis of brain death is established on the basis of a combination of clinical signs and paraclinical methods. Diffusion-weighted MRI is a new method sensitive to cerebral ischemia. Its value in brain death has not been demonstrated until now. Case Description

A Method for Registering Diffusion Weighted Magnetic Resonance Images [PDF]
, 2006 Diffusion weighted magnetic resonance (DWMR or DW) imaging is a fast evolving technique to investigate the connectivity of brain white matter by measuring the self-diffusion of the water molecules in the tissue. Registration is a key step in group analysis of the DW images that may lead to understanding of functional and structural variability of the ...
