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.
