^(18)F-FDG PET/CT显像与^(99m)Tc-MDP全身骨显像诊断骨转移的价值

Comparison of ^(18)F-FDG PET/CT and ^(99m)Tc-MDP whole body bone scan in detection of bone metastases

目的评价18F-脱氧葡萄糖(FDG)PET/CT与99mTc-亚甲基二膦酸盐(MDP)ECT全身骨显像对骨转移肿瘤的诊断价值。方法对29例经病理或临床证实的恶性肿瘤患者进行18F-FDGPET/CT显像与99mTc-MDPECT全身骨显像,并评价显像效果。结果26例肿瘤患者18F-FDGPET/CT显像为阳性,其中有17例患者发现骨转移45处;在99mTc-MDPECT全身骨显像中,有20例患者发现骨转移77处。结论18F-FDGPET/CT显像对恶性肿瘤具有较高的诊断价值,而99mTc-MDPECT全身骨显像是诊断骨转移的常规方法。

Objective To evaluate the diagnostic value of ^18 F-FDG PET/CT and ^99mTc-MDP ECT in detection of bone metastases. Methods ^18F-FDG PET/CT and ^99mTc-MDP ECT whole body bone scan were performed in 29 patients with various tumors. Results The results of ^18F-FDG PET/CT were positive in 26 patients, 17 cases with bone metastases were detected. In the patients who performed ^99mTc-MDP ECT,20 cases with bone metastasses were found. Conclusion ^99mTc-MDP ECT whole body bone scan has been usually used as the imaging modality of choice in the diagnosis of bone metastases, while ^18 F-FDG PET/CT is a valuable method in the diagnosis of malignant tumors.
