Non-contrast, cranial computed tomography (NCCT) scan showing a wedge-shaped hypodensity (yellow arrow) demarcating core infarct (unsalvageable brain) B. Computed tomography angiogram showing occlusion of the left middle cerebral artery C. Automated perfusion scan (RAPID software iSchemaView, Menlo Park, CA) showing the area of core infarct in pink (upper right, 130cc) and the entire area at risk in green (lower right, 209cc) giving an estimated 79cc (209cc-130cc) of penumbra (affected but salvageable brain) (Created with BioRender.com).
