This article discusses the basics of unenhanced MR angiography (MRA) and MR venography (MRV), time-resolved contrast-enhanced (CE) MRA and dynamic first-pass CE perfusion MRI, and unenhanced and CE MRV, in addition to assessing the clinical relevance of these techniques for evaluating patients with suspected pulmonary thromboembolism and deep venous thrombosis.
Since the 1990s, the efficacy of MRA or MRV and dynamic perfusion MRI for patients with suspected pulmonary thromboembolism and deep venous thrombosis has been evaluated. On the basis of the results of single-center trials, comprehensive MRI protocols, including pulmonary unenhanced and CE MRA, perfusion MRI, and MRV, promise to be safe and time effective for assessing patients with suspected pulmonary thromboembolism, although future multicenter trials are required to assess the real clinical value of MRI.
本文讨论了非增强磁共振血管造影（MRA）和磁共振静脉造影（MRV）、时间分辨对比增强（CE）MRA和动态首过CE灌注磁共振成像的基础，以及非增强和CE MRV，此外还评估了这些技术在评估疑似肺血栓栓塞症和深静脉血栓形成患者时的临床相关性。
自20世纪90年代以来，已对MRA或MRV以及动态灌注磁共振成像在疑似肺血栓栓塞症和深静脉血栓形成患者中的疗效进行了评估。基于单中心试验的结果，包括肺部非增强和CE MRA、灌注磁共振成像和MRV的综合磁共振成像方案，有望在评估疑似肺血栓栓塞症患者时安全且高效，但未来需要多中心试验来评估磁共振成像的实际临床价值。
