Low-dose whole-brain dynamic 4D CTA DSA and perfusion, enabled by wide-area CT and AiCE DLR. The 4D CTA shows a blood flow interruption of the right MCA-M3 segment. Perfusion maps display reduced regional cerebral blood flow and increased MTT in M3 territory corresponding to the vascular abnormality.
