Abstract

Computed tomography angiography (CTA) offers a rapid means of evaluating the vasculature of the head and neck in patients presenting with acute onset of neurologic symptoms and blunt trauma to the head and neck. CTA is noninvasive, easy to acquire, and offers excellent detail in identifying site and nature of the lesion. The learning objectives of this article are to review normal anatomy and variants, recognize CTA appearance of vascular pathologies, describe typical parameters used for acquiring the study, and recognize common pitfalls.
