Abstract

Recent developments in the use of magnetic resonance (MR) imaging to measure and image molecular diffusion and blood microcirculation (perfusion) hold significant promise in the evaluation of anatomic and functional disorders of the brain. Although diffusion and perfusion are often conceptually mixed, they actually refer to different phenomena. Molecular diffusion is the result of the thermal, so-called Brownian, spontaneous random translational motion that involves all molecules. Perfusion, in contrast, relates to blood delivery to the tissues.
