Noninvasive Diagnosis of Blunt Cerebrovascular Injuries: A Preliminary Report

Abstract

CTA and MRA can identify BCVI, but they miss grade I, II, and III injuries. Future technical modifications may improve their accuracy. A prospective multicenter trial is warranted to define the capabilities and limitations of these noninvasive modalities. In the interim, arteriography remains the gold standard for diagnosis, but if arteriography is not available, CTA or MRA should be used to screen for BCVI in patients at risk.
