We implemented an end-to-end cardiac self-gating algorithm for a novel free-breathing 2D cine phase-contrast sequence on a clinical MRI scanner. We validated our technique against clinically performed ECG-gated cine phase-contrast scan. Strong agreement with no statistically significant difference was shown between the systemic and pulmonary blood flow measurements calculated between the standard ECG-gating and self-gating scans. Our approach eliminates the need for an ECG signal and allows for blood flow measurements where an ECG is not accessible such as fetal cardiac MRI.
