Fig. 2From: Regional computed tomography perfusion deficits in patients with hypoglycemia: two case reportsNcCT, CTA, and CTP of patient 2. Exemplary cuts of first ncCT (A), CTA (B), and CTP (C–F) 70 min after onset of symptoms. CTA without relevant stenosis but with elongation of extra- or intracranial vessels (B). Follow-up ncCT 24 h after onset (not shown) did not show infarct demarcation compared to first ncCT (A). Hypoperfusion in left frontal and left parieto-temporo-occipital areas on TTP with Tmax of > 6 s (D–F) and smaller reduced perfusion on CBF (C) marked with circle. CBF, cerebral blood flow; CT, computed tomography; CTA, CT Angiography; CTP, CT Perfusion; ncCT, non-contrast CT; Tmax, time-to-maximum; and TTP, time-to-peakBack to article page
