The study will look at how repeatable the NaF PET scans are before treatment. Scans will also be performed after standard chemotherapy or hormone-directed treatment. This will allow evaluation of how the NaF PET scans change with the chemotherapy or hormone-directed therapy. In addition, NaF PET scans will be compared with standard computed tomography (CT) and bone scans, as well as prostate specific antigen (PSA). This information could be used to develop better ways to measure prostate cancer bone lesions. In turn, this could be used to better evaluate treatment effects of standard chemotherapy and other new drugs being developed to treat prostate cancer.
