The Adult Patient with Acute Neurologic Deficit: An Update on Imaging Trends

Neuroimaging Clinics of North America

Abstract

Stroke is the clinical syndrome of abrupt onset of acute neurologic deficit owing to decreased oxygen delivery to the brain, resulting in ischemia or infarction. Approximately 87% of strokes are ischemic and 13% are hemorrhagic. Improved awareness of the neuroimaging findings highlighted in recent stroke clinical trials, as well as of their role in patient selection for novel treatment options-including "late window" (8-24 hours post-ictus!) intraarterial thrombectomy-has become increasingly important. This article focuses on the role of neuroimaging in the assessment and management of patients with acute ischemic stroke.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.
