A multitransmit external body array combined with a 1 H and 31 P endorectal coil to enable a multiparametric and multimetabolic MRI examination of the prostate at 7T.

ABSTRACT: PURPOSE:In vivo 1 H and 31 P magnetic resonance spectroscopic imaging (MRSI) provide complementary information on the biology of prostate cancer. In this work we demonstrate the feasibility of performing multiparametric imaging (mpMRI) and 1 H and 31 P spectroscopic imaging of the prostate using a 31 P and 1 H endorectal radiofrequency coil (ERC) in combination with a multitransmit body array at 7 Tesla (T). METHODS:An ERC with a 31 P transceiver loop coil and 1 H receive (Rx) asymmetric microstrip (31 P/1 H ERC) was designed, constructed and tested in combination with an external 8-channel 1 H transceiver body array coil (8CH). Electromagnetic field simulations and measurements and in vivo temperature measurements of the ERC were performed for safety validation. In addition, the signal-to
