In this abstract, we proposed a novel technique for imaging coronary vessel wall. A self-gated free-breathing multi-echo radial imaging technique was used to generate 3D coronary cine images. No external respiratory, cardiac gating or dedicated preparation pulses were required. Simultaneous water and fat visualization was achieved, and the combination of the two images has been demonstrated to not only improve the coronary artery contrast but provide depiction of the coronary artery vessel wall.
