Fig. 2From: Agreement between estimated computed tomography perfusion ischemic core and follow-up infarct on diffusion-weighted imagingBland–Altman plot comparing the estimated CTP ischemic core volume and DWI follow-up infarct volume. The mean bias (blue), lower (red) and upper (green) limits of agreement are shown with 95% confidence intervals. The bias with 95% confidence intervals is shown in blue. Negative values indicate overestimation by CTP. CTP  CT perfusion, DWI  diffusion weighted imagingBack to article page
