Diffusion Magnetic Resonance Imaging
Diffusion Weighted MRI
MRI, Diffusion Weighted
Magnetic Resonance Imaging, Diffusion
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 (ADC) with time, as reflected by tissue microstructure. Diffusion MRI has been used to study BRAIN ISCHEMIA and tumor response to treatment.
