MR Diffusion

MR diffusion-weighted images (DWI) detect changes in the mobility of free molecular protons. In all biological systems, the free diffusion of proton is limited by physical barriers such as cell membranes or chemical interactions such as bonding to micromolecules. Comparison of this limited diffusion with the diffusion characteristics of free water can provide information on the physical and physiologic conditions of tissue.
