Figure 4From: Rapid identification of a major diffusion/perfusion mismatch in distal internal carotid artery or middle cerebral artery ischemic stroke DWI and mismatch volumes of entire prospective cohort in order of time after stroke onset. Abnormal DWI volume of each patient is depicted as a dark gray bar. Light gray bars represent the DWI/TTP mismatch. Horizontal lines delineate volumes of 70 ml and 100 ml. All patients with DWI lesion volume of 70 ml or less had at least 100% mismatch volume. There was no significant correlation between time from stroke onset and DWI lesion volume or between time and mismatch volume. DWI: Diffusion weighted imaging; TTP: Time to peak.Back to article page
