Valvular disease example: aortic regurgitation. a Left ventricular outflow tract view in diastole showing aortic regurgitation jet (arrow) in a 56-year-old woman presented with heart failure. b Aortic through-plane phase contrast with magnitude and phase images of the same patient. c Aortic flow curve demonstrating quantitative analysis of forward aortic flow and regurgitant flow as negative flow persisted through the entire diastole (shaded area). This was post-processed from the phase contrast images (b)
