Pulmonary hypertension (PH) is defined by a mean pulmonary artery pressure greater than 20 mmHg and classified into five different groups sharing similar pathophysiologic mechanisms, haemodynamic characteristics, and therapeutic management. Radiologists play a key role in the multidisciplinary assessment and management of PH. A working group was formed from within the Fleischner Society based on expertise in the imaging and/or management of patients with PH, as well as experience with methodologies of systematic reviews. The working group identified key questions focusing on the utility of CT, MRI, and nuclear medicine in the evaluation of PH: Is noninvasive imaging capable of identifying PH? What is the role of imaging in establishing the cause of PH? How does imaging determine the severity and complications of PH? How should imaging be used to assess chronic thromboembolic PH before treatment? Should imaging be performed after treatment of PH? This systematic review and position paper highlights the key role of imaging in the recognition, work-up, treatment planning, and follow-up of PH.
肺动脉高压（PH）定义为平均肺动脉压大于 20mmHg，并分为五个不同组，它们具有相似的病理生理机制、血流动力学特征和治疗管理。放射科医生在 PH 的多学科评估和管理中发挥着关键作用。一个工作组由 Fleischner 学会内部组成，其成员在 PH 患者的影像学和/或管理方面具有专业知识，并且在系统评价方法方面具有经验。工作组确定了关注 CT、MRI 和核医学在 PH 评估中的应用的关键问题：非侵入性成像是否能够识别 PH？成像在确定 PH 病因中的作用是什么？成像如何确定 PH 的严重程度和并发症？在治疗前应如何使用影像学评估慢性血栓栓塞性 PH？PH 治疗后是否应进行影像学检查？本系统评价和立场文件强调了影像学在识别、检查、治疗计划和 PH 随访中的关键作用。
