CT and MR Measurements in Pulmonary Hypertension
摘要
Pulmonary hypertension (PH) is diagnosed by finding a mean pulmonary arterial pressure (mPAP) of more than 20 mmHg at rest when measured invasively at right heart catheterisation (RHC) (Humbert et al. 2022). The haemodynamics of mPAP at RHC are a function of both diastolic and systolic pulmonary artery pressure (dPAP and sPAP, respectively) and are calculated as mPAP = (2/3 × dPAP) + (1/3 × sPAP).
