Note.—Values are the mean ± SD. ROICONTIG indicates the mirror ROI of the infarct growth lesion; ROICONTINF, mirror ROI of the final infarct. Ratios were determined as the mean signal intensity or ADC values for ROIDWICORE, ROIIG, or ROIFINAL or for ROICONTIG or ROICONTINF divided by the mean value of the ROI in the affected vascular territory in the contralateral hemisphere.
