We present a comparison of a newly designed dual-channel, rigid endorectal coil for both imaging and spectroscopic imaging of the prostate with a standard, single-channel, inflatable endorectal coil, demonstrating a SNR improvement of up to ~500% in the near-coil area (where the prostate peripheral zone is located), and up to ~150% at depth (where the prostate central zone is located). This huge SNR improvement allows for greatly improved MR/MRSI imaging of the prostate.
