Intracranial Aneurysms: Detection with Three-dimensional CT Angiography with Volume Rendering—Comparison with Conventional Angiographic and Surgical Findings

Abstract

CT angiography has good sensitivity for depiction of intracranial aneurysms 3 mm or larger and relatively good sensitivity for aneurysms less than 3 mm. CT angiography may be a noninvasive technique for detection of asymptomatic unruptured or ruptured aneurysms.
