Fluorine-18 Fluorodeoxyglucose (F-18 FDG) PET/CT is established as a powerful imaging tool for cancer detection and monitoring response to therapy. However, not all cancers are identified reliably due to variable rates of glucose metabolism. Sodium Fluorine-18 (F-18) was used in the 1970s for bone scanning and can be used as a skeletal tracer in current PET/CT scanners. The combined administration of F-18 and F-18 FDG in a single PET/CT scan for cancer detection was not attempted to date. However, such an approach has the potential to improve cancer diagnosis, staging, prognosis, and therapy monitoring. The combination of these technologies may also allow for shorter imaging times, lower costs, as well as improved screening or earlier cancer detection. The investigators will attempt a pilot study with 10 patients to acquire the preliminary results needed to proceed with additional 90 subjects.
