Magnetic resonance angiography (MRA) of the pulmonary arteries still is a rapidly evolving technique with already proved high clinical usefulness. Contrast-enhanced and non-contrast-enhanced angiographic techniques are widely available for high spatial or real-time imaging of the pulmonary arteries. Multiple step protocols, such as perfusion MR imaging followed by high spatial resolution contrast-enhanced MRA, seem to be an optimal clinical approach for the assessment of different vascular diseases affecting the pulmonary arteries. This review article describes the MR imaging techniques available and their application in acute and chronic thromboembolic disease.
肺动脉磁共振血管造影（MRA）仍是一项快速发展的技术，其临床实用性已得到证实。对比增强和非对比增强血管造影技术广泛应用于肺动脉的高空间分辨率或实时成像。多步骤方案，如灌注磁共振成像后进行高空间分辨率对比增强MRA，似乎是评估影响肺动脉的不同血管疾病的最佳临床方法。这篇综述文章描述了现有的磁共振成像技术及其在急性和慢性血栓栓塞性疾病中的应用。
