The whole brain, infarct lesion, brain template, and infarction template were selected for ROIs. Infarct volume (%)=infarct lesion (mm3) / whole brain (mm3)×100 without template volume. Mean, SD, min, and max were also automatically calculated by IRW in the infarct lesion for the brain excluding the template.
