Pulmonary hypertension (PH) is a life-threatening condition, characterized by elevated pulmonary arterial pressure, which is confirmed based on invasive right heart catheterization (RHC). Noninvasive examinations may support diagnosis of PH before proceeding to RHC and play an important role in management and treatment of the disease. Although echocardiography is considered a standard tool in diagnosis, recent advances have made computed tomography (CT) and magnetic resonance (MR) imaging promising tools, which may provide morphologic and functional information. In this article, we review image-based assessment of PH with a focus on CT and MR imaging.
CT may provide useful morphologic information for depicting PH and seeking for underlying diseases. With the accumulated technological advancement, CT and MRI may provide practical tools for not only morphologic but also functional assessment of patients with PH.
肺动脉高压（PH）是一种危及生命的病症，其特征是肺动脉压升高，这一诊断基于有创的右心导管检查（RHC）。在进行 RHC 之前，非侵入性检查可能有助于 PH 的诊断，并在疾病的管理和治疗中发挥重要作用。尽管超声心动图被认为是诊断的标准工具，但最近的进展使计算机断层扫描（CT）和磁共振（MR）成像成为很有前途的工具，它们可以提供形态和功能信息。在本文中，我们重点介绍 CT 和 MR 成像，综述 PH 的基于影像的评估。
CT 可提供有用的形态学信息，有助于 PH 的描述和潜在疾病的寻找。随着技术的不断进步，CT 和 MRI 不仅可为 PH 患者的形态学评估，也可为功能评估提供实用工具。
