Summary:

      This phase II trial studies how well 11C-choline (carbon C 11 choline) and 18F-choline
      (fluorine F 18 choline) positron emission tomography/magnetic resonance (PET/MR) imaging
      works in diagnosing patients with unfavorable intermediate to high-risk prostate cancer.
      Diagnostic procedures, such as 11C- and 18F-choline PET/MR may help find and diagnose
      prostate cancer and find out how far the disease has spread.

          -  Have a medical condition or other circumstances which, in the opinion of the
             investigator would significantly decrease the chances of obtaining reliable data,
             achieving the study objectives, or completing the study.
