In this study, we demonstrate that a dipole transceive antenna array with a loop coil receive array at 7T substantially outperforms state of the art 3T MRI of the prostate. Using this setup we demonstrated for the first time the intrinsic SNR benefits of using the higher field strength of 7 tesla for prostate MR imaging compared to a clinically used prostate imaging setup at 3 tesla: an overall gain in SNR of 2.1 fold as obtained in 6 subjects.
