Imaging modalities in acute ischemic stroke

Abstract

As "time is brain", acute ischemic stroke is considered a medical emergency. With the introduction of thrombolytic therapy and availability of modern neuroimaging modalities, timely diagnosis of an ischemic lesion, exclusion of intracerebral hemorrhage, assessing the degree of brain injury, and evaluation of cerebral vasculature is necessary in acute stroke management. In this review we will highlight the importance of available imaging modalities used to assess patients with acute ischemic stroke.
