  1. In vivo scan parameters for qDSA and 4D Flow MRI. Identical scans were used for all vessel locations, including: Iliac, right renal, left renal, common hepatic, splenic. MRI time frames is the number of reconstructed volumes for a cardiac cycle. The velocity encoding (VENC) was set to 100 cm/s in order to capture velocities from all abdominal vessels in a single scan
