Evaluation of the Vestibular System by Magnetic Resonance Angiography

Abstract

Abstract This report describes the normal arterial patterns of the vestibulocerebellar regions visualized by magnetic resonance angiography. Variations in the vertebrobasilar arterial system are described, limitations in imaging are discussed, and collateral connections within the cerebellar vessels and the circle of Willis are reviewed. Clinical correlations are defined between the vestibular nuclei, the associated intra‐axial tracts, and with specific posterior cerebral and brain stem arteries.
