Pulmonary embolism (PE) is one of the most frequently encountered clinical emergencies. The diagnosis often involves multiple diagnostic tests, which need to be carried out rapidly to assist in the safe management of the patient. Recent strides in computed tomography (CT) have made big improvements in patient management and efficiency of diagnostic imaging. This review article describes the developments in magnetic resonance (MR) techniques for the diagnosis of acute PE. Techniques include MR angiography (MRA) and thrombus imaging for direct clot visualization, perfusion MR, and combined perfusion-ventilation MR. As will be demonstrated, some of these techniques are now entering the clinical arena, and it is anticipated that MR imaging (MRI) will have an increasing role in the initial diagnosis and follow-up of patients with acute PE.
肺栓塞（PE）是最常见的临床急症之一。诊断通常需要进行多项诊断测试，这些测试需要迅速开展，以协助对患者进行安全管理。计算机断层扫描（CT）技术的最新进展在患者管理和诊断成像效率方面取得了重大进步。这篇综述文章描述了用于急性肺栓塞诊断的磁共振（MR）技术的发展。这些技术包括磁共振血管造影（MRA）和用于直接观察血栓的血栓成像、灌注磁共振成像以及灌注 - 通气联合磁共振成像。正如将要展示的那样，其中一些技术现已进入临床领域，预计磁共振成像（MRI）在急性肺栓塞患者的初始诊断和随访中将发挥越来越重要的作用。
