Intra-arterial catheter angiography has, in the past, been the mainstay for the investigation of intracranial vascular disease. It is, however, invasive, usually requires in-patients admission, and is associated with a rate of neurological complications between 1% and 3%. In recent years, magnetic resonance angiography (MRA) and CT angiography (CTA) have emerged as non-invasive alternatives for imaging blood vessels and have made a significant impact on neuroradiological investigations. It is the purpose of this article to explain the basic technical principles of these two methods and to give an overview of their current clinical applications.
过去，动脉内导管血管造影术一直是颅内血管疾病检查的主要手段。然而，它具有侵入性，通常需要住院，且伴有1%至3%的神经并发症发生率。近年来，磁共振血管造影（MRA）和CT血管造影（CTA）已成为血管成像的非侵入性替代方法，并对神经放射学检查产生了重大影响。本文旨在解释这两种方法的基本技术原理，并概述它们目前的临床应用。
