Comparison of right coronary artery images derived from the same subject at (left) 7.0 T and (right) 3.0 T [47]. Gradient echo imaging (TR/TE/FA 4.3 ms/1.38 ms/15°, data matrix 512×312) using a spatial resolution of (0.82×0.82×2) mm³ was performed. For signal transmission and reception, a local quadrature coil was used at 7.0 T. A large-volume body coil was used for excitation at 3.0 T in conjunction with a six-element cardiac optimized receive array. At this early stage of the development, this study shows that 7.0-T RCA images can already be acquired with image quality comparable to those using much more sophisticated many element RF coil receive arrays at 3 T
