GUMDROP : NCI 12-c-0080 NaF PET/CT repeatability, responsiveness & response assessment in mCRPC to bone w/ either docetaxel or AR-directed therapies 

Description:The purpose of this research study is to evaluate a newer imaging technique, called 18F-Sodium Fluoride (NaF) positron emission tomography (PET). NaF is a tracer (dye) that is very sensitive for changes in bone. By using this tracer with positron emission tomography/computed tomography (PET/CT) imaging, our ability to evaluate and measure changes in bone lesions could be greatly improved.
