Core Tip

Core Tip: This work investigated the diagnostic value of technetium-99m-methylene diphosphonate (99mTc-MDP) single photon emission computed tomography (SPECT)/ CT imaging combined with the serum prostate-specific antigen (PSA)/free PSA ratio for detecting bone metastasis in prostate cancer (PC). Compared to individual methods, the combination of SPECT/CT imaging and PSA/fPSA ratio demonstrated significantly higher positive predictive values and specificity. The PSA/fPSA ratio in PC bone metastasis (PCBM) patients was notably lower than in non-PCBM patients. The integrated approach achieved a 95% detection rate for PCBM, emphasizing its diagnostic efficacy.
