肺动脉高压(PH)定义为右心导管法测得的静息平均肺动脉压≥为25毫米汞柱。PH是一种进行性的、危及生命的疾病，病因多种多样。快速准确地诊断肺高压，并在病因组中进行适当的分类，将有助于早期治疗和改善预后。在PH的评估中使用了许多成像工具，如胸部X光、计算机断层扫描(CT)、通风/灌注(V/Q)扫描和心脏磁共振成像。新的成像工具，如双能CT和单光子发射计算机断层扫描/计算机断层扫描也出现了；然而，它们在PH诊断评估中的地位仍有待确定。一般来说，每种成像技术都提供了不同程度的敏感性和特异性的增量信息，这有助于怀疑PH的存在并确定其病因。本研究旨在对可用于评估PH患者的成像方式的效用、优点和缺点进行全面的综述。
Pulmonary hypertension (PH) is defined as resting mean pulmonary artery pressure ≥25 mmHg measured by right heart catheterization. PH is a progressive, life-threatening disease with a variety of etiologies. Swift and accurate diagnosis of PH and appropriate classification in etiologic group will allow for earlier treatment and improved outcomes. A number of imaging tools are utilized in the evaluation of PH, such as chest X-ray, computed tomography (CT), ventilation/perfusion (V/Q) scan, and cardiac magnetic resonance imaging. Newer imaging tools such as dual-energy CT and single-photon emission computed tomography/computed tomography V/Q scanning have also emerged; however, their place in the diagnostic evaluation of PH remains to be determined. In general, each imaging technique provides incremental information, with varying degrees of sensitivity and specificity, which helps suspect the presence and identify the etiology of PH. The present study aims to provide a comprehensive review of the utility, advantages, and shortcomings of the imaging modalities that may be used to evaluate patients with PH.
