目的探讨FDG PET/CT显像诊断骨或软组织肿瘤和术后疗效评价的价值。方法回顾性分析48例已证实的骨及软组织肿瘤患者的FDG PET/CT显像结果,以鉴别诊断肿瘤的良恶性,是否复发、有无其他转移及周围侵犯,并与同机CT对比分析。结果 FDGPET/CT显像诊断骨及软组织肿瘤灵敏度为100%(7/7),特异性为80%(4/5);监测术后复发(残留)的灵敏度和特异性均为100%;通过PET/CT显像多发现转移灶35处,对于肺部12个转移灶,有赖于同机CT。结论 FDG PET/CT显像对骨及软组织肿瘤的诊断优于常规影像检查,可早期准确判断肿瘤复发,同时发现更多转移灶(肺转移除外),对肿瘤治疗诊断有指导作用。
Objective To investigate the value of FDG PET / CT in the diagnosis of bone or soft tissue tumors and postoperative evaluation. Methods The results of FDG PET / CT in 48 cases of confirmed bone and soft tissue tumors were retrospectively analyzed to differentiate the benign and malignant tumors, whether they relapsed or not, whether there was any other metastasis or peripheral invasion, and compared with CT. Results The sensitivity and specificity of FDG PET / CT in the diagnosis of bone and soft tissue tumors were 100% (7/7) and 80% (4/5) respectively. The sensitivity and specificity of FDG PET / CT were 100% PET / CT imaging found more than 35 metastases, 12 lung metastases, depends on the same CT. Conclusion FDG PET / CT imaging is superior to routine imaging in the diagnosis of bone and soft tissue tumors. It can accurately determine tumor recurrence early and find more metastases (except for lung metastasis), which can guide the diagnosis and treatment of tumors.
