Fig. 3From: Imaging predictors of procedural and clinical outcome in endovascular acute stroke therapyFavorable collaterals in a 67-year-old with acute right MCA occlusion. Axial maximum intensity projection (MIP) of the CTA show a right M1 segment MCA occlusion (a) with excellent collateral filling of the affected territory (a, b). Correlative CTP shows no CBV evidence of a completed core infarct (c, d). A large ischemic penumbra is evident on the Tmax maps (e, f). Colorized threshold maps demonstrate a small region of core infarct (pink, g) with a relatively large territory at risk (green, h)Back to article page
