DWI is sensitive to restriction of Brownian motion of extracellular water … WebDWI is an MRI technique that is extremely sensitive for the detection of cytotoxic edema. It is highly specific and sensitive (> 95% for both) for the detection of acute ischemic infarcts and can differentiate acute from chronic infarctions. It has high signal-to-noise ratio and excellent interrater reliability.
