Figure 3.

DWI and mismatch volumes of entire retrospective 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 DWI/MTT mismatch. Horizontal lines demarcate volumes of 70 ml and 100 ml. All patients with DWI lesion volume 70 ml or less had at least a 100% mismatch. There was no significant correlation between time from stroke onset and DWI lesion volume or between time and mismatch volume. DWI: Diffusion weighted imaging; MTT: Mean transit time.
