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).
