Imaging findings OR Procedure details
At Pilgrim Hospital ( District General Hospital) in Boston in Lincolnshire UK.
188 patients were admitted with symptoms and signs of acute stroke from Accident and Emergency department during 3 months period to Stroke Word
(14)% 25 patients had negative CT imaging scans and the diagnosis was confirmed with Diffusion awaited MRI
The area of acute ischemic infarction becomes hyperintense (bright) on
early diffusion-weighted images because of the shift of water from extracellular to intracellular compartments in the formation of cytotoxic edema that results from failure of sodium potassium ATPase function
caused by a net drop in the apparent diffusion coefficient (ADC) of water
