ABSTRACT
The detail and information obtained from neuroimaging have improved greatly over the
last two decades with the advent of magnetic resonance imaging (MRI) and angiography
(MRA). In the last decade, advances in computer technology and tomography have produced
angiographic images from computed tomography (CTA). Despite these advances, the basic
evaluation of traumatic vascular injury relies on catheter angiography. With advances
in critical care and neuroimaging techniques, it has become feasible to have critically
ill patients undergo MR and CT imaging. MRA and CTA provide the ability to diagnose
rapidly and noninvasively vascular injuries that may predispose to stroke. The purpose
of this article is to review briefly these advances and their relevance to traumatic
brain injury for the neurosurgical practitioner.
