The different components of the right heart pulmonary circulation unit can be investigated by MRI and computed tomography. MRI has clear advantages over echocardiography for accurate definition of right heart function and structure and to derive functional information regarding the pulmonary vasculature. Computed tomography is superior for the assessment of parenchymal and vascular pathologies of the lung with indications in the diagnostic work-up of pulmonary hypertension, but with more limited capability to evaluate right ventricular function and in deriving pulmonary hemodynamics. Recent technical developments with these imaging modalities could allow a better evaluation of the right heart pulmonary circulation unit.
右心-肺循环单元的不同组成部分可通过 MRI 和计算机断层扫描进行研究。MRI 在准确定义右心功能和结构以及获取有关肺血管系统的功能信息方面优于超声心动图。计算机断层扫描在评估肺部实质和血管病变方面优于超声心动图，适用于肺动脉高压的诊断性检查，但评估右心室功能和推导肺血流动力学的能力有限。这些成像方式的最新技术发展可以更好地评估右心-肺循环单元。
