Velocity Quantification by Electrocardiography-Gated Phase Contrast Magnetic Resonance Imaging in Patients With Cardiac Arrhythmia: A Simulation Study Based on Real Time Transesophageal Echocardiography Data in Atrial Fibrillation

Conclusions: The PC MRI velocity measurements in patients with varying RR interval durations are not significantly different from time-averaged real-time velocity data for a typical segmented k-space data acquisition schemes. Though beat-to-beat variations in atrial velocities that were observed with TEE cannot be detected with ECG-gated multibeat PC MRI, it can reliably assess average flow patterns across multiple beats
