Accuracy of Three-Dimensional Gadolinium-Enhanced MR Angiography in the Assessment of Extracranial Carotid Artery Disease

Abstract

Used alone, 3D gadolinium-enhanced MR angiography is not accurate enough to replace conventional angiography in the evaluation of extracranial carotid arteries. In association with duplex Doppler sonography, however, it is accurate and may obviate a significant number of conventional angiographic examinations.
