Acute Human Stroke Studied by Whole Brain Echo Planar Diffusion-Weighted Magnetic Resonance Imaging
Ann Neurol 37:231-241, Warach,S.,et al, 1995

Article Abstract
Our purpose was to use whole brain echo planar magnetic resonance imaging (MRI)to identify and characterize diffusion abnormalities in acute cerebral ischemia.We studied 40 patients as early as 3 hours after onset of signs and symptoms of cerebral ischemia.Diffusion-weighted imaging(DWI) of the entire brain could be completed in 3 seconds or,using seven different diffusion sensitivities(maximum b=1,271 sec/mm2),in 48 seconds. DWI with echo planar imaging measures a unique physiological parameter that is sensitive to ischemic changes before conventional MRI.Its potential role in the quantitative study of human stroke pathophysiology and therapeutics is the subject of further investigation.
