Magnetic resonance angiography (MRA) is gaining wide acceptance as a screening modality for the intracranial vasculature. Previous reports have demonstrated that MRA is capable of accurately depicting the normal vascular anatomy and anatomic variants. To date various techniques have been applied in the evaluation of vaso-occlusive disease, aneurysms, arteriovenous malformations and venous sinus thrombosis. Recent technical developments have significantly improved spatial resolution and vascular contrast and will further enhance its routine clinical use. The purpose of this essay is to summarize the technical approaches, clinical role and limitations of MRA as they apply to the intracranial circulation.
