Figure Lengend Snippet: Exemplary images processed by the new multimodal FD-CT approach. 66-year-old male with a proximal M1 occlusion right, NIHSS 21. NE-FDCT on which the demarked infarct of the anterior third of the right MCA-territory can be delineated ( A and B ; arrowheads). FD-CTA shows a clear visualization of the cervical vasculature ( C ; dashed arrows) and a proximal occlusion of the right M1-segment ( D ; continuous arrow). FD-CTP shows a matching deficit in the color-coded maps of RAPID ANGIO (1–4) and of the Siemens perfusion prototype software (5–8) as they show a delay for Tmax (1) and TTP (5), MTT (2 and 6) and a reduction for CBF (3 and 7) and CBV (4 and 8). Automated perfusion analysis using RAPID ANGIO revealed a small mismatch between the infarct core, estimated by the CBF reduction (pink), and the potential salvageable tissue, estimated by the delayed Tmax (green), which results into a mismatch ratio of 1.2 (E)
