Radiol Clin North Am. 2019 Nov;57(6):1109-1116. doi: 10.1016/j.rcl.2019.06.003. Epub 2019 Jul 30.


Occlusion of a cervical or cerebral artery may cause acute ischemic stroke (AIS). Recent advances in AIS treatment by endovascular thrombectomy have led to more widespread use of advanced computed tomography (CT) imaging, including perfusion CT (PCT). This article reviews PCT for the evaluation of AIS patients.
