The whole-heart coronary MRA with compressed sensing (CS) technique is a novelly noninvasive, contrast agent-free, and radiation-free technique for evaluating coronary artery disease[2] [3].Patients with atrial fibrillation have irregular heartbeat, which brings uncertainty to the coronary MRA image quality. Results of this study indicated that there was no statistical difference in coronary artery image quality with CS acceleration factors of 2, 4, 6 between sinus rhythm and atrial fibrillation patients, which suggested that whole-heart coronary MRA with CS technique could also be applied inpatients with atrial fibrillation.
