In patients with suspicious bone metastasis, the clinical impact of PET/CT for differential diagnosis and primary lesion identification could differ according to 18F-FDG uptake patterns. We report the findings in patients with suspicious bone metastasis who underwent PET/CT for the evaluation of the primary lesion site and were classified in a stepwise manner, first based on the multiplicity of positive bone uptake and then the presence of extraskeletal uptake.
