We collected 4D flow MRI data and right heart catheterization (RHC) data from 20 idiopathic pulmonary artery hypertension (IPAH) patients and applied parameter analysis. The results indicate the difference of the flow characteristics in the main pulmonary artery (MPA) between the patients with right ventricle (RV) function loss and the patients with normal RV function. To conclude, 4D flow MRI is a good tool to detect hemodynamics and has the potential to assist in evaluating the state and the curative effect of IPAH.
