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.
