With rapid advancements in imaging technology, cardiac computed tomography (CT) and magnetic resonance (MR) imaging are increasingly being used for anatomic evaluation, functional assessment, and pathologic diagnosis of the pulmonary valve and right ventricle. MR imaging is especially helpful in evaluating postoperative pulmonary valve function and grading of pulmonary regurgitation. On the other hand, CT has the advantage of high-resolution isovolumetric whole-chest coverage and is able to depict anatomic detail of the pulmonary valve, perivalvular structures, and pulmonary artery branches.
随着影像学技术的快速发展，心脏计算机断层扫描（CT）和磁共振（MR）成像越来越多地用于肺动脉瓣和右心室的解剖评估、功能评估和病理诊断。MR 成像特别有助于评估肺动脉瓣术后功能和肺动脉瓣反流分级。另一方面，CT 具有高分辨率容积式全胸部覆盖的优势，并能够描绘肺动脉瓣、瓣周结构和肺动脉分支的解剖细节。
