Direct measurement of coronary artery motion can be determined from a Cartesian 2D fat image navigator, which uses a spatial-spectral selective excitation to excite the epicardial fat surrounding the coronary arteries. In this study, we demonstrate the feasibility of motion correction on all acquired data in a 3D SSFP CMRA sequence without respiratory gating using coronary artery displacements derived from the 2D Fat image navigator.
