HELICAL BLOOD FLOW IN PULMONARY ARTERY VISUALIZED WITH PHASE-RESOLVED 3D CINE PHASE CONTRAST MRI (4D-FLOW)

The pulmonary circulation is impaired by various diseases and the analysis of pulmonary blood flow has great clinical significance. 4D-Flow can visualize the velocity vectors of blood flow as streamline images. We aimed to study changes in flow pattern of pulmonary artery (PA) during a cardiac cycle
