The aim of this study was to compare the diagnostic and prognostic values of (99m)Tc-MDP-planar bone scintigraphy ((99m)Tc-MDP-BS), (131)I single-photon emission computed tomography/computed tomography ((131)I-SPECT/CT) and (18)F-fluorodeoxyglucose ((18)F-FDG)-PET/CT for the detection of bone metastases from differentiated thyroid cancer (DTC). ⋯ (131)I-SPECT/CT and (18)F-FDG-PET/CT demonstrated high diagnostic performance in detecting bone metastases from DTC. (99m)Tc-MDP-BS might be completely replaced by (131)I-SPECT/CT in combination with ((131)F-FDG-PET/CT in the management of DTC patients with bone metastases. (18)F-FDG-PET/CT positivity was an independent factor associated with poor prognosis.
