Artificial intelligence software for assessing brain ischemic penumbra/core infarction on computed tomography perfusion: A real-world accuracy study

Figure 2 Imaging findings regarding cerebral perfusion, core infarction, and cerebral arteries of case 2. A: Shukun brain perfusion computed tomography (CT) image processing software suggested that the core infarction volume was 5.7 mL (pink area), the low perfusion volume was 4.2 mL (blue area), and the mismatch volume was negative; B: Digital subtraction angiography of the head and neck indicated M1 segment occlusion of the left middle cerebral artery (arrow); C: Cranial CT image showing a large area of cerebral infarction in the left hemisphere 7 days after mechanical thrombectomy (triangle).
