Diffusivity / Kurtosis Mismatch in Acute Ischemic Stroke : Potential Indicator of Reversible Ischemic Injury

Introduction Diffusion-weighted imaging (DWI) detects ischemic lesion within minutes after stroke onset, significantly earlier than conventional relaxation MRI [1]. Ischemic lesion with mean diffusivity (MD) abnormality has often been considered as ischemic core in which tissue is proceeding to infarction. However, MD lesion, if reperfused promptly, is… (More)
