99mTcO4-甲状腺显像评估分化型甲状腺癌术后残甲的价值分析郑贵文，夏志明，姚树展山东第一医科大学附属省立医院核医学科山东济南250021【摘要】目的探讨分化型甲状腺癌术后、131I治疗前99mTcO4-甲状腺显像评估残甲的临床应用价值。方法选取我科收治的56例分化型甲状腺癌患者，测定甲状腺蛋白(Tg)、甲状腺球蛋白抗体(TgAb)、促甲状腺激素(TSH)，行99mTcO4-甲状腺显像、131I显像。分析99mTcO4-甲状腺显像灵敏度、特异度、准确度、阳性预测值、阴性预测值、残甲灶检出率，残甲摄鍀计数与Tg/TSH相关性。结果99mTcO4-甲状腺显像灵敏度86．79%，特异度66．67%，准确度85．71%，阳性预测值97.87%，阴性预测值22．22%，残甲灶检出率69．23%。残甲摄鍀计数与Tg/TSH显著相关(r=0．617，P＜0．01)。结论分化型甲状腺癌术后、131I治疗前99mTcO4-甲状腺显像评估残甲临床应用价值较高，具有较高的灵敏度和阳性预测价值以及令人满意的残甲灶检出率。残甲摄鍀计数与Tg/TSH两者显著相关。【关键词】分化型甲状腺癌;131I治疗;99mTcO4-甲状腺显像;单光子发射计算机断层显像中图分类号:Ｒ736．1;Ｒ814．43文献标识码:A文章编号:1006-9011(2023)04-0559-04Thevalueof99mTcO4-thyroidscanindetectingremnantthyroidtissueindifferentiatedthyroidcancerZHENGGuiwen，XIAZhiming，YAOShuzhanDepartmentofNuclearMedicine，ShandongProvincialHospitalAffiliatedtoShandongFirstMedicalUniversity，Jinan250021，Chi-na【Abstract】ObjectiveToexplorethevalueof99mTcO4-thyroidscanindetectingremnantthyroidtissueinthyroidectomizeddifferentiatedthyroidcancer．Methods56patientswithdifferentiatedthyroidcanceradmittedtoourdepartmentwereselected．Tg，TgAbandTSHweredetermined，and99mTcO4-thyroidscanand131Iscanwereperformed．Thesensitivity，specificity，accu-racy，positivepredictivevalue，negativepredictivevalueanddetectionrateofremnantthyroidtissue，aswellasthecorrelationbe-tweentechnetiumresiduecountandTg/TSHof99mTcO4-thyroidscanwereanalyzed．ＲesultsThesensitivity，specificity，accu-racy，positivepredictivevalue，negativepredictivevalueanddetectionrateofremnantthyroidtissueof99mTcO4-thyroidscanwere86.79%，66．67%，85．71%，97．87%，22．22%and69．23%，respectively．Technetiumresiduecountsweresignificantlycorr...
