Within minutes of an acute cerebral ischemic insult, diffusion-weighted magnetic resonance imaging (DWI) demonstrates ischemic regions with a decline in the apparent diffusion coefficient (ADC) of water.

Animal studies and preliminary observations in humans demonstrate that initial DWI and ADC abnormalities are reversible by early reperfusion.
