Cross-sectional view of a 5-year-old, 20 kg, single-ventricle patient status-post Glenn palliation demonstrating locations of 4D Flow quantification (black circles) positioned perpendicular to the axis of the vessel. Venous structures in diastole (left image) and arterial structures in systole (right image) were acquired in a single acquisition. Arterial and venous structures sampled include: right superior vena cava (RSVC), left superior vena cava (LSVC), left pulmonary artery (LPA), left upper pulmonary vein (LUPV), left lower pulmonary vein (LLPV), inferior vena cava (IVC), right lower pulmonary vein (RLPV), right upper pulmonary vein (RUPV), right pulmonary artery (RPA), and the aorta
