Toward the Era of a One-Stop Imaging Service Using an Angiography Suite for Neurovascular Disorders

Figure 2

A 67-year-old man with left middle cerebral artery (MCA) occlusion. (a) Noncontrast computed tomography (CT) demonstrated a hyperdense MCA sign (arrow) and excluded intracranial hemorrhage. (b) Flat-detector CT (FDCT) angiography demonstrated the total occlusion of left MCA (arrow). (c) A parenchymal cerebral blood volume (FDCT-PBV) map depicted a large area of hypoperfusion in the corresponding left MCA territory, which was similar to the results of multidetector CT perfusion imaging (not shown). (d) After intra-arterial mechanical thrombectomy, recanalization of the left MCA was demonstrated by FDCT angiography. (e) An FDCT-PBV map depicted the recovery of CBV values (circle) in part of the hypoperfused parenchyma after revascularization.
