Echocardiography is currently the gold standard for cardiac tissue velocity measurement . Phase contrast MRI with multiple excitations averaging has been proposed as an alternative solution . In this study, we used a central k-space line phase contrast sequence  to acquire real-time velocity curves and compared them to echocardiography.
This new method provides velocity curves very similar to echocardiographic tissue Doppler ones and the measurements of duration of the main cardiac cycle components (systole, diastasis) as well as MPI were well correlated. This paves the way for the observation of beat to beat intra-subject variability of cardiac indices.
