Multiphase CT Angiography: A New Tool for the Imaging Triage of Patients with Acute Ischemic Stroke.
To describe the use of an imaging selection tool, multiphase computed tomographic (CT) angiography, in patients with acute ischemic stroke (AIS) and to demonstrate its interrater reliability and ability to help determine clinical outcome. ⋯ Multiphase CT angiography is a reliable tool for imaging selection in patients with AIS.
