Fig. 1From: Regional computed tomography perfusion deficits in patients with hypoglycemia: two case reportsNcCT, CTA, and CTP of patient 1. Exemplary cuts of first ncCT (A), CTA (B), and CTP (C–D) 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-peakBack to article page
