ObjectivesThe purpose of this study was to investigate the sensitivity of F-18 fluoride and F-18 fluorodeoxyglucose (FDG) positron-emission tomography (PET) in the diagnosis of bisphosphonate-related osteonecrosis of the jaw (BRONJ), and to test their suitability for assessing the severity of BRONJ.Study designNine patients with BRONJ were studied using F-18 fluoride and F-18 FDG PET. For analysis, 8 regions of interest (ROI) were defined in the jaws of each patient. Maximum count rates for each ROI in both PET examinations were analyzed.ResultsIn both studies, increased tracer enhancement was observed in regions with BRONJ. Uptake of fluoride significantly exceeded that of FDG. FDG uptake increased systematically, but not significantly, with increasing severity of BRONJ.ConclusionF-18 fluoride PET is a sensitive method for diagnosis of BRONJ. FDG PET could be useful for evaluation of the severity of BRONJ. Further studies are required to prove the specificity of the methods.
