为对９９ｍ Ｔｃ－ＭＩＢＩ显像、１３１Ｉ－ＷＢＳ和ＨＴＧ 测定，在分化型甲状腺癌１３１Ｉ治疗后随访中的价值进行对比研究，对５３例分化型甲状腺癌患者依次行ＨＴＧ 测定、９９ｍ Ｔｃ－ＭＩＢＩ显像和１３１Ｉ－ＷＢＳ。结果：９９ｍ Ｔｃ－ＭＩＢＩ显像的灵敏度、特异性和准确性分别为８６．３６％ 、８７．１０％ 、８６．７９％ ；ＨＴＧ 测定和１３１ Ｉ－ＷＢＳ灵敏度分别为６８．１８％ 和６３．３４％ ，特异性为１００％ ，准确性分别为８６．７９％ 和８４．９１％ 。三者联合检查总灵敏度达１００％ ，特异性和准确性分别为８７．１０％ 和９２．４５％ 。结论：９９ｍ Ｔｃ－ＭＩＢＩ显像具有较高的灵敏度。９９ｍ Ｔｃ－ＭＩＢＩ显像、１３１ Ｉ－ＷＢＳ和ＨＴＧ 测定联合检查有助于进一步提高诊断的灵敏度和准确性。 To compare the value of 99m Tc-MIBI imaging, 131I-WBS and HTG in the follow-up of differentiated thyroid carcinoma treated with 131I, 53 cases of differentiated thyroid cancer patients were followed by HTG assay, 99m Tc-MIBI Like and 131I-WBS. Results: The sensitivity, specificity and accuracy of 99m Tc-MIBI imaging were 86.36%, 87.10% and 86.79%, respectively. The sensitivity of HTG and 131 I-WBS were 68.18% and 63% respectively. 34%, 100% specificity, accuracy of 86.79% and 84.91% respectively. The three combined examination of the total sensitivity of 100%, specificity and accuracy were 87.10% and 92.45%. Conclusion: 99m Tc-MIBI imaging has higher sensitivity. 99m Tc-MIBI imaging, 131 I-WBS and HTG assay combined to help further improve the diagnostic sensitivity and accuracy.
