18F-FDG PET与99Tcm-MDP显像对肿瘤骨转移的诊断价值

  目的 探讨18F-FDG PET与99Tcm-MDP显像对肿瘤骨转移的诊断价值。方法 93例肿瘤患者2周内行18F-FDG PET和99Tcm-MDP显像，比较分析两种显像结果。结果 93例肿瘤患者PET和MDP诊断骨转移64例。64例骨转移患者中PET和MDP阳性43例，PET阳性而MDP阴性16例，PET阴性而MDP阳性5例。18F-FDG PET和99Tcm-MDP显像诊断骨转移的灵敏度分别为92.2 %，75.0 %（P＜0.05）；特异度分别为93.1 %，79.3 %（P＞0.05）；准确度分别为92.5 %，76.3 %（P＜0.01）。结论 18F-FDG PET诊断肿瘤骨转移的灵敏度和准确性显著高于99Tcm-MDP显像。18F-FDG PET对骨转移有一定的诊断价值。

Diagnostic value of 18F-FDG PET and 99Tcm-MDP imaging in detection bone metastases

Objective To investigate the diagnostic value of 18F-FDG PET and 99Tcm-MDP imaging in detection bone metastases. Methods 93 patients were undergone 18F-FDG PET and 99Tcm-MDP imaging within 2 weeks. The results of the 2 different modalities were analyzed. Results Of the 93 patients, 64 patients were found to have bone metastases by PET and MDP imaging. Among the 64 patients, 43 patients were found both positive PET and MDP. 16 patients had positive PET whereas negative MDP. 5 patients had negative PET whereas positive MDP. The sensitivity, specificity and accuracy of 18F-FDG PET and 99Tcm-MDP imaging were 92.2 %, 75.0 %(P < 0.05), 93.1 %, 79.3 %(P > 0.05), 92.5 %,76.3 %(P < 0.01), respectively. Conclusion 18F-FDG PET is more sensitivity and higher accuracy than 99Tcm-MDP imaging. 18F-FDG PET is helpful in detection bone metastases.
