From: Non-invasive pediatric cardiac imaging—current status and further perspectives
(4D flow MRI): characterization of flow dynamics of the great thoracic vessels (oblique antero-lateral view) in a healthy preterm fetus. Blood flow direction and velocity are indicated by velocity-coded streamlines (DAo descending aorta, AAo ascending aorta, MPA main pulmonary artery, ductus arteriosus). The advent of 4D techniques simplified the demonstration and understanding of even complex vascular anomalies
