found: MeSH browser, Oct. 11, 2005(Diffusion Magnetic Resonance Imaging. Scope note: A diagnostic technique that incorporates the measurement of molecular diffusion (such as water or metabolites) for tissue assessment by MRI. The degree of molecular movement can be measured by changes of apparent diffusion coefficient with time as reflect by tissue microstructure. Diffusion MRI has been used to study brain ischemia and tumor response to treatment. Entry term: Diffusion Weighted MRI)

found: Wikipedia, Oct. 11, 2005(Diffusion MRI: a specific magnetic resomance imaging (MRI) modality that produces in vivo images of biological tissues weighted with the local microstructural characteristics of water diffusion. Traditionally, in diffusion-weight imaging, usually three gradient-directions are applied, sufficient to estimate the trace of the dissuion tensor or average diffusivity, a putative measure of oedema.)
