Diffusion-weighted magnetic resonance imaging

Diffusion-weighted magnetic resonance imaging — also called diffusion magnetic resonance imaging or diffusion weighting imaging (DWI) — is an imaging technique based on the Nuclear magnetic resonance principle in which measures of diffusion are incorporated into the process of image generation.

" The degree of molecular movement can be measured by changes of apparent diffusion coefficient (ADC) with time, as reflected by tissue microstructure. Diffusion MRI has been used to study brain ischemia and tumor response to treatment."
