Keywords: Flow, Quantitative ImagingDiastolic function evaluation requires estimates of early and late diastolic mitral valve flow velocities (E and A), and mitral annulus tissue velocity (e’). Our goal was to develop a bSSFP phase-contrast (PC) sequence (PC-SSFP) for in-plane flow-encoding, for simultaneous recording of E and A, and estimation of e’ based on tracking mitral valve motion on cine magnitude images, in a single breath-hold. Phantom and in vivo experiments showed agreement of PC-SSFP with velocities on GRE-based PC providing similar velocity curves, while achieving the high SNR and contrast of bSSFP cine images.
