Coronary MRA has been implemented on a 7 tesla human system and tested on eleven volunteers. Adaptations from protocols at lower field strengths include the optimization of navigators, fat suppression and vector ECG placement, as well as volume selective power optimization using a transmit/receive surface coil due to the absence of available body coils at 7 tesla. MRAs were successfully obtained from all subjects, allowing quantitative measurements of RCA diameter and length, as well as vessel sharpness.
