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

Figure 1 Imaging findings regarding cerebral perfusion, core infarction, and cerebral arteries of case 1. A: Shukun brain perfusion computed tomography image processing software suggested that the core infarction volume was 4 mL located in the right cerebral hemisphere (pink area), and the low perfusion volume of 246.1 mL mainly in the left hemisphere (blue area); B: Digital subtraction angiography revealed M1 segment occlusion of the left middle cerebral artery (arrow); C: Diffusion-weighted imaging revealed infarction in the left cerebral hemisphere 14 days after mechanical thrombectomy (triangle).
