Conventional subtracted whole-body CE-MRA is time-consuming and requires experiences for operators. Instead, one-stop subtractionless CS-MRA in our study could depict the whole-body arterial vasculatures with only once contrast injection and only 0.15 mmol/kg dose, which assisted by multiple techniques including reverse k-space filling mode, total imaging matrix system, automatic table moving, automatic coil selection and especially the CS technique. The comparative results supported it feasible with accepted image qualities and a faster acquisition time in clinical use.
