Multiparametric MRI (mpMRI) is a valuable tool to assess aggressiveness and stage of localized prostate cancer. When combined with metabolic information from ¹H and ³¹P spectra valuable information on the metabolism of the disease can be derived. Here we demonstrate a dual element endorectal coil with ¹H Rx and ³¹P TxRx capabilities combined with an external 8-channel transmit-receive body array. One patient (Gleason score 4+4) was measured. High quality proton spectra show elevated total choline in tumor tissue, which corresponded with increased glycerophosphocholine, glycerophosphoethanolamine and phosphocholine in the ³¹P spectra of the tumor.
