Measurement levels for aortic flow measurements. a: Level 1: below aortic valve, Level 2: at the aortic valve, Level 3: aortic sinus, Level 4: sinotubular junction, Level 5: ascending aorta at the level of the pulmonary arteries, Level 6: ascending aorta below the brachiocephalic trunk. b/c: 4D flow image at the level of the pulmonary arteries and visualization of the regurgitant aortic jet (arrow)
