We have developed a 3D cones alternating-TR steady state free precession (SSFP) sequence for whole-heart coronary MR angiography (CMRA). In this study, we compare motion artifacts and coronary image quality between a sequential-cones and phyllotaxis-cones sequence. Coronary image quality was analyzed using qualitative scores obtained through blinded reading by two board-certified cardiologists, and the IEPA vessel sharpness metric. The results of the study show that the phyllotaxis-cones acquisition can alleviate motion artifacts, improve qualitative image quality scores and increase coronary vessel sharpness.
