Objective: Flat detector CT perfusion (FD-CTP) imaging is a new modality that permits rapid assessment of the state of perfusion in the angiography suite. We present a case in which FD-CTP was useful for the determination of the therapeutic strategy for embolism that occurred during angiography.

Case Presentation: Cerebral angiography performed before surgery for brain tumor suggested left posterior cerebral artery occlusion. Since the judgment of whether it was chronic occlusion or embolism that occurred during the examination was difficult, FD-CTP was performed. As hypoperfused area was observed in the left occipital lobe without previously known infarction, the lesion was judged not to be chronic occlusion but to possibly cause cerebral infarction without treatment. We immediately performed thrombectomy and prevented its development into cerebral infarction.

Conclusion: FD-CTP was useful for the diagnosis and determination of the therapeutic strategy for intracranial vascular occlusion as a complication of cerebral angiography because it can be promptly performed in the angiography suite.
