Fig. 3

4D-CMR flow of the MPA, RPA, and LPA of a surgically repaired TOF patient with RV-PA conduit. a Vector field maps showing the velocity and direction of blood flow across pulmonary arteries during systole (arrows). This type of visualization provides a quick overview of velocity fields. b Streamlines color map showing also the forward flow across pulmonary arteries during systole. This type of visualization is useful to visualize 3D velocity fields at discrete time points. A high-systolic velocity across the RPA is noted by the two methods (red color map). CMR: cardiac magnetic resonance, MPA: main pulmonary artery, RPA: right pulmonary artery, LPA: left pulmonary artery, TOF: tetralogy of Fallot
