©2013 UpToDate ® Print Email Acute ischemic stroke on CT angiography source image An 88-year-old woman admitted with acute left hemiparesis and dysarthria 90 minutes after the onset of symptoms. Baseline noncontrast head CT (A) shows early ischemic changes in the right MCA territory (arrows). CTA-SI image (B) reveals hypoattenuation in the right MCA territory (arrows), which corresponds to the final infarct (C) on follow-up CT scan (arrows). MCA: middle cerebral artery; CTA-SI: CT angiography source image. Reproduced with permission from: Bhatia R, Bal SS, Shobha N, et al. CT angiographic source images predict outcome and final infarct volume better than noncontrast CT in proximal vascular occlusions. Stroke 2011; 42:1575. Copyright © 2011 Lippincott Williams & Wilkins.
