Prostate cancer is one of the most common diseases in men, and using multimodality, hybrid systems, such as MR-PET provides valuable data for early diagnosis. A human prostate is quite flexible and can move into different positions under external conditions so it is important to localise the critical region-of-interest using both MRI and PET under the same circumstances. In this study, we focused on various MRI RF coil designs suitable for use in MR-PET prostate imaging, and investigated their performance by evaluating SNRs and penetration depths as a function of coil tilting angle against B₀.
