NcCT, CTA, and CTP of patient 1. Exemplary cuts of first ncCT (A), CTA (B), and CTP (CD) 87 min after onset of aphasia. CTA without relevant stenosis of extra- or intracranial vessels (B). Follow-up ncCT 31 h after onset (not shown) did not show infarct demarcation compared to first ncCT (A). Hypoperfusion parieto-temporal on TTD (C) and smaller reduced perfusion on CBF (D) marked with circle. Only mild delay (2 s) was detected in corresponding TTP. CBF, cerebral blood flow; CT, computed tomography; CTA, CT angiography; CTP, CT perfusion; ncCT, non-contrast CT; TTD, time-to-drain; and TTP, time-to-peak
