Coronary MR imaging at 7.0T has the potential to improve imaging quality. The objective of this work is to demonstrate the feasibility of comprehensive coronary artery MR imaging at 7.0T, including all three major coronary arteries. Imaging is performed using a novel 8-channel transmit receive array with modified dipole antennas. The LCX and LAD have been imaged successfully in respectively 4 and 5 out of 7 cases; the RCA in 5 out of 5. Image quality is good while there is even room for improvement. The results provide a promising showcase that coronary artery imaging is feasible at 7 Tesla.
