From: Stability of large diffusion/perfusion mismatch in anterior circulation strokes for 4 or more hours
Diffusion weighted images from all 14 patients. Images were selected at the level of maximum lesion growth for each patient. The baseline, 4 hour, 24 hour and 1 week time points are displayed. The DWI hyperintense abnormalities did not change in most patients at 4 hours after baseline. However, there was an obvious increase in lesion volume by 24 hours after baseline in most patients, as well as at the 1 week time point.
