Figure 6: Patient with a right ICA occlusion underwent right superficial temporal artery-middle cerebral artery (STA-MCA) bypass surgery for right hemispheric ischemic symptoms. Time-resolved CTA (A) done after the surgery shows the patent bypass channel (A). Whole brain CTP (B and C) done before (B) and after (C) the surgery shows a marked increase in CBF (arrow) and CBV (arrow) and a relative decrease in MTT (arrow) and TTP (arrow) in the right middle cerebral artery distribution. However, the MTT and TTP continued to be elevated (arrows in C)
