Neurovascular MR angiography (MRA) is an evolving imaging technique and is crucial for the workup of numerous neurologic disorders. While CT angiography (CTA) provides a more rapid imaging assessment, in select patients it can impart a small risk of contrast material-induced nephrotoxicity or radiation-associated cancers. In addition, MRA offers some advantages over CTA for neurovascular evaluation, including higher temporal resolution and the capability for vessel wall imaging. This module is the third in a series created on behalf of the Society for Magnetic Resonance Angiography (SMRA), a group of researchers and clinicians who are passionate about the benefits of MRA but understand its challenges.

神经血管磁共振血管造影（MRA）是一种不断发展的成像技术，对许多神经疾病的诊断至关重要。虽然 CT 血管造影（CTA）提供了更快速的成像评估，但在某些特定患者中，它可能会带来较小的对比剂诱导的肾毒性或辐射相关癌症的风险。此外，MRA 在神经血管评估方面具有一些优于 CTA 的优势，包括更高的时间分辨率和血管壁成像能力。本模块是代表磁共振血管造影学会（SMRA）创建的一系列模块中的第三个，该组织由热衷于 MRA 益处但了解其挑战的研究人员和临床医生组成。美国政府的工作成果以与 RSNA 的独家许可形式发布。
