BACKGROUND AND PURPOSE In ischemic stroke, perfusion-weighted imaging (PWI) and diffusion-weighted imaging (DWI) provide important pathophysiological information. A PWI>DWI mismatch pattern suggests the presence of salvageable tissue. However, improved methods for distinguishing PWI>DWI mismatch tissue that is critically hypoperfused from benign oligemia are required. METHODS We investigated the usefulness of maps of relative cerebral blood flow (rCBF), volume (rCBV), and mean transit time… CONTINUE READING
