Overall image quality. Comparison of overall image quality for radial self-navigated non-contrast-enhanced magnetic resonance angiography (radial MRA, n = 31) and contrast-enhanced MRA (CE-MRA, n = 61) at the three aortic locations rated as excellent (orange), good (light orange), moderate (light gray) and poor (dark gray). The black line separates the two groups for binary ratings in “excellent/good/moderate” versus “nondiagnostic”. CE-MRA contrast-enhanced magnetic resonance angiography
