摘　　要：目的探讨放射性核素显像诊断儿童异位甲状腺(ETG)的价值及显像剂的合理应用。方法对83例疑诊ETG患儿进行甲状腺核素显像检查,其中采用131I显像55例,99mTcO4-显像30例(两者联用2例)。并与临床病理检查结果比较。结果病理检查诊断为ETG 11例。核素显像对11例ETG全部检出,诊断ETG的敏感性、特异性131I均为100%,99mTcO4-亦均为100%;但99mTcO4-较131I图像明显清晰。结论放射性核素显像对儿童ETG的诊断具有独特价值,宜常规选择99mTcO4-显像。Objective To evaluate the value of radionuclide imaging in the diagnosis of children＇s ectopic thyroid gland （ETG） and the reasonable application of radionuclide imaging agents. Methods Eighty-three suspected ETG children were performed with radionuclide imaging, of which 53 cases were given 131I as imaging agent,28 cases were injected 99TcO4^-, and 2 cases used both of them. The imaging results were compared with the Clinical and pathological results. Resuits Eleven cases were diagnosed as ETG. The sensitivity and specialty of 131I and 99mTcO4^- were both 100%. But the imaging results with 99mTcO4^- were much clearer than those with 131I. Conclusion The significance of radionuclide imaging in the clinical diagnosis of ETG is affirmatory, 99mTcO4^- should be chosen as the routine radionuclide imaging agent.
