High-resolution prostate imaging for both 3T and 7T MRI are challenging, given the deep location of this exocrine gland which accentuates technical issues related to the reduced electromagnetic penetration and B₁ inhomogeneity. In this work, high-resolution (0.3 x 0.3mm in-plane) non-interpolated T2w-TSE prostate images from a healthy volunteer were acquired at 3T using a commercial 18-channel body matrix and 32-channel spine coil and an 8-channel prototype coil at 7T at 15 slices and 11 slices, respectively. Compared with standard clinical prostate imaging at 3T, the 7T prostate images provided higher SNR and better differentiation of various zones of the prostate.
