This clinical trial studies how well fludeoxyglucose F-18 (18FDG) and fluorine F18 16-beta-fluoro-5-alpha-dihydrotestosterone (18FDHT) positron emission tomography (PET) works in treating patients with prostate cancer that is growing, spreading, or getting worse. FDG and FDHT PET may help locate tumor cells and learn what they use to grow to improve treatment in patients with progressive prostate cancer.

PRIMARY OBJECTIVES:
I. To study the accumulation and biodistribution of FDHT in patients with progressive prostate cancer.
II. To define the relationship between FDHT uptake and tumor diffusivity as assessed by magnetic resonance imaging (MRI).
III. To preliminarily determine the relationship between FDHT uptake and tissue analyses of androgen receptor (AR) expression (tissue will not be acquired under this protocol).
IV. To correlate the accumulation of 18FDHT to 18FDG.
V. To study changes in 18FDHT accumulation over time in patients treated with castration and other hormones and chemotherapy.
OUTLINE:
Patients receive 18FDG intravenously (IV) and undergo PET imaging over 60-75 minutes on day 1. Patients then receive fluorine 18FDHT IV and undergo PET imaging on day 2. Some patients will only receive 18FDG or 18FDHT IV and undergo PET imaging on day 1. Courses repeat at weeks 4 and 12, and every 12 weeks for up to 8 FDHT/FDG scan sets in 12 months.
