[11C] choline positron emission tomography (PET) is an emerging modality for staging at initial diagnosis or re-staging at the time of treatment failure. The updated study shows 11C -labeled choline derivatives seem to be the most promising PET radionuclides in assessment of prostate cancer and USA FDA approves the utility of C-11 Choline in prostate cancer patients in 2012 September.
To our best literature search, there are only few preliminary studies regarding application of PET/MR in prostate cancer patients and the initial results in correlation of functional MRI and PET images seems promising. Combined PET/MRI images have the advantage of giving anatomical, functional, and metabolic information in a single image setting and provide a comprehensive survey including local regional extension and systemic metastasis. Unlike in the USA where more than 70% prostate cancer patients were diagnosed at early stage, most prostate cancer patients in Taiwan were diagnosed at advanced stage with high PSA or T3-4 disease, or even systemic metastasis. The need to implement good staging modality is even more urgently needed in Taiwan than in USA and related studies are still lacking. In the current study, our hypothesis is that C-11 Choline PET/MRI is a good modality in staging high risk prostate cancer patients, and in predicting patients' outcome after treatment. Our hypothesis will be examined by this clinical study.

This is an uncontrolled, open-labeled, non-randomized, prospective study. The study duration is expected to be completed in a period of 2 years. Up to 54 patients with primary prostate cancer and stratified as high risk group (PSA > 20 ng/mL, or Gleason score 8-10, or clinical stage >T2c) would be included.
- The Role of C-11 Choline PET in Patients with Prostate Cancer [ Time Frame: Two years ]Inconsistence rate (%) of C-11 Choline PET and MRI in detecting local regional and distant metastasis prostate cancer. The inconsistence rate (%) is defined as the proportion of inconsistent results by PET and MRI, i. e. PET positive but MRI negative, or PET negative but MRI positive.
