11例早期肺癌^(99)Tc^m-MIBI肺显像诊断价值探讨

Study on ^(99)Tc^m MIBI lung imaging in 11 cases of early lung cancer

目的 探讨应用 99Tcm -甲氧异丁基异腈 (MIBI)肺显像诊断早期肺癌的价值。方法 收集经手术与病理证实的 1 1例 期肺癌病例 ,进行 99Tcm- MIBI肺显像并与 X线片、 CT检查准确率回顾对照分析。结果 1 1例患者平面显像有 8例阳性考虑恶性 ,另 3例平面显像阴性 ;其中阴性 2例补充断层显像发现异常浓聚灶 ,考虑为恶性。核素显像符合率 90 .91 %。 CT扫描结果提示肺癌 4例 ,肺结核 2例 ,5例无法定性 ;CT定性诊断准确率 4 4 %。结论 应用 99Tcm-

Objective To diagnose early lung cancer with 99 Tc m MIBI.Methods 11 cases of early lung cancer confirmed by patholgy and operationwere collected and retrospectively to compare the analyzed for accumcy of 99 Tc m MIBI lung imaging with X ray and CT examination.Results Of 11 cases,8 cases were positive and considered as malignancies. Other 3 cases were negative on plane imaging. CT imaging showed abnormal density collective focus in 2 cases of negative ones.Coincidence rate of radionuclide imaging was 90 91%.CT scanning suggested that there were 4 cases of lung cancer,2 of TB and 5 without determinable nature.Accuracy of CT diagnosis was 44%.Conclusion 99 Tc m MIBI lung imaging is an efficient and sensitive way to diagnose lung tubercle qualitatively.
