摘要：
This article reviews the various imaging modalities available for the evaluation of patients presenting with a potential stroke syndrome, specifically acute ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage. It reviews the various computed tomography (CT) modalities, including noncontrast brain CT (NCCT), CT angiography, and CT perfusion. It discusses multimodal magnetic resonance imaging in the evaluation of patients with acute stroke, including diffusion-weighted imaging, T2-weighted sequences/fluid-attenuated inversion recovery, magnetic resonance angiography, perfusion-weighted imaging, and gradient-recalled echo. At the end of this article, a brief review on how to read an NCCT geared toward the emergency physician is included.
