Although digital subtraction angiography (DAS) remains the gold standard for neurovascular imaging, the number of diagnoses made on the basis of less invasive cross-sectional imaging techniques (CT and MR angiography) is increasing. The present article provides important technical principles of CT and MR angiography, followed by an analysis of the diagnostic possibilities and limitations of vascular cross-sectional imaging. The particular importance of post-processing of vascular cross-sectional datasets is also discussed. Using the typical clinical diagnostic work-up of extra- and intracranial vascular diseases as a basis, the article explains how a suitable examination technique and protocol is chosen and which limitations need to be borne in mind. After taking at look at the technical advances expected in the future (3-Tesla MRA, dual-energy CTA, post-processing workflow in PACS), the remaining indications for diagnostic DSA will be presented and explained.
尽管数字减影血管造影（DAS）仍是神经血管成像的金标准，但基于侵入性较小的横断面成像技术（CT血管造影和MR血管造影）做出的诊断数量正在增加。本文介绍了CT血管造影和MR血管造影的重要技术原理，随后分析了血管横断面成像的诊断可能性和局限性。还讨论了血管横断面数据集后处理的特殊重要性。本文以颅外和颅内血管疾病的典型临床诊断流程为基础，解释了如何选择合适的检查技术和方案，以及需要牢记哪些局限性。在审视了未来预期的技术进展（3特斯拉MRA、双能CTA、PACS中的后处理工作流程）之后，将介绍并解释诊断性DSA的其余适应症。
