Radiographic Evaluation of Unruptured Cerebral Aneurysms

Abstract

Intracranial vascular imaging plays an important role in the diagnosis, risk assessment and treatment planning of unruptured intracranial aneurysms (UIAs). In this review article, we will discuss the various imaging modalities commonly employed in the imaging of UIAs including computed tomography and MR Angiography highlighting the technological advancements, strengths and drawbacks for each modality. The different techniques of 3-dimensional digital subtraction angiography, high resolution cone beam computed technology (HR-CBCT), the different clinical scenarios in which HR-CBCT can prove useful, and the pathology that enables the neurointerventionalist to make better informed decisions ultimately leading to better patient outcomes, are also discussed.
