In this study, we compare a 8-stripline coil array with a endorectal coil. FDTD simulations are performed to evaluate the SAR deposition of both coils. Given the power restrictions due to these SAR levels, the suitability of the coils is tested for three common imaging protocols for prostate cancer: a T1w image, a T2w image and MR spectroscopy. Results show that a surface coil array is needed for T1w and T2w images, while the endorectal coil is needed for spectroscopy.
