- W2364076816 abstract "Objective To assess the val ue of 18-fluorodeoxy glucose (~18F-FDG) positron emission tomography( PE T)-CT in the detection of malignant bone metastases. Methods Thirty-five out of 332 patients, 89 lesions were detected on ~18 F-FDG PET-CT and were interpreted separately on PET, combined CT, and fused PE T-CT images. Results Of the 89 lesions detected on PET- CT images, 68 were malignant and 21 were benign lesions. PET alone identified 62 malignant lesions and 17 benign lesions. The diagnostic sensitivity, specificit y, and accuracy of PET alone for diagnosis of bone metastases were 91.2% (62/68) , 81.0% (17/21), and 88.8% (79/89), respectively. The combined CT alone identifi ed 55 malignant lesions and 16 benign lesions. The diagnostic sensitivity, s pecificity, and accuracy of combined CT alone were 80.9% (55/68), 76.2% (16/21), and 79.8% (71/89), respectively. The fused PET-CT images identified 64 maligna nt and 19 benign lesions. The diagnostic sensitivity, specificity, and accuracy of the fused PET-CT were 94.1% (64/68), 90.5% (19/21), and 93.2% (83/89), respe ctively. Conclusion In the diagnosis of bone metastases, ~18F-FDG PET-CT imaging reduces the false positive rate and increases the specificity. ~18F-FDG PET-CT imaging is helpful in the differentiation o f bone metastases from benign lesions." @default.
