C11-Sodium Acetate PET/CT Imaging for Metastatic Disease in Intermediate-to-high Risk Prostate Adenocarcinoma

OBJECTIVES: * Determine the role of positron emission tomography using carbon-11 acetate (AC-PET) in the initial and subsequent management of patients with prostate cancer at intermediate or high risk for recurrence after initial curative therapy. * Compare the value of AC-PET in predicting recurrence of prostate cancer with that of conventional approaches (e.g., pre-operative clinical staging, prostate-specific antigen, Gleason score, prostate and lymph node histology) in these patients.
