Whole-heart coronary MRA is challenging due to the long data acquisition time on the order of 8-12 minutes. The purpose of this work was to optimize a radial EPI technique for contrast-enhanced whole-heart coronary MRA, with the goal of combining the scan efficiency of EPI with the motion insensitivity of radial sampling.
