Pre-Diamox computed tomographic perfusion (CTP) study showing a large region of asymmetric diminished cerebral blood flow (CBF) and elevated mean transit time and time to peak within the right middle cerebral artery territory, with few small interspersed regions of decreased cerebral blood volume (CBV). Post-Diamox CTP study showing increased degree of asymmetric decreased CBF and elevated mean transit time (MTT)/time to peak (TTP) abnormality within the portion of the right middle cerebral artery territory, with unchanged region of matched CBV defect
