Coronary artery blood flow measurements by phase-contrast MRI have been limited by heart motion and the minute size of the coronary arteries. In this study, a navigator-echo gated cine phase velocity mapping technique is described to obtain velocity and flow waveforms of the coronary arteries at 3T. Six right coronary arteries and six left anterior descending coronary arteries were studied with measurable cross-sections in 182/192 (94.8%) total phases.
