Phase-contrast peak velocity measurement through cardiac valves has important clinical applications, but is widely known to underestimate peak velocity. This abstract evaluated whether Fourier Velocity Imaging (FVI) in aortic stenoses avoids the underestimation by standard phase-contrast cine imaging (PC), and compares FVI with Doppler echocardiography (US).
