In recent years, several probes have been developed to allow for the intraoperative detection of tumor tissue using [18F]fluorodeoxyglucose (FDG). Detector designs include high-energy γ and β probes, as well as combination devices with background rejection capabilities. Some laboratory prototypes and commercialized systems have demonstrated reasonable sensitivities for 511 keV photons and/or b particles emitted from 18F for in vivo use. This review focuses on the ability of these devices to detect tumor deposits in the low-contrast environment of the operating room. Important technical and biological factors that influence tumor-to-background contrast are discussed and potential future applications and developments are highlighted. In addition, we evaluate the limited data on absorbed doses resulting from [18F]FDG administration immediately prior to surgery that indicate acceptable levels of radiation exposure to operating room personnel.
