The use of an endorectal 31P coil at high magnetic field strength might provide opportunities to sample signals from energy and phospholipid compounds with a clinically relevant spatial resolution in the prostates of patients with prostate cancer. We present a double tuned coil concept that can be fit inside the housing of an endorectal balloon coil design so that it can be positioned close to the organ for optimum receive performance. The double tuned coil design was built and tested for SNR in comparison with two single resonant coils (1H and 31P).
