彩色多普勒超声与^(99m)Tc-MIBI对甲状腺冷结节性质的比较研究

Comparison of color doppler ultrasonography with ^(99m) Tc-MIBI in cold nodules of thyroids

目的目的:探讨彩色多普勒超声(CDFI)与99mTc-MIBI显像对甲状腺“冷”结节良恶性的诊断价值。方法对99mTcO4-显像提示为“冷”结节的182例患者,次日行99mTc-MIBI显像及CDFI检查,所有病例均经手术病理证实。结果99mTc-MIBI和CDFI诊断甲状腺癌的敏感度、特异度、准确率分别为69.8%和86.8%,88.4%和91.5%,83.0%和90.1%;两者联合应用时,甲状腺癌诊断的敏感度、特异度、准确率分别达到90.6%、95.3%、94.0%。结论CDFI结合99mTc-MIBI显像对鉴别甲状腺“冷”结节的良恶性具有较大的临床应用价值。

Objective To study the diagnostic role of color Doppler flow imaging （CDFI） and 99m^Tc-MIBI in cold nodules of thyroids.Methods CDFI and 99m^Tc-MIBI were used to detennine the cold nodules of thyroids in 182 patients undergoing 99m^TcO4^-; imaging. All patients underwent surgery and pathological examination. Results The sensifivity, specificity and accuracy in the evaluation of malignant thyroid nodules were 69.8 %, 88.4% and 83.0% by 99m^Tc-MIBI, and 86.8 %, 91.5 % and 90.1% by CDFI, and 90. 6%,95.3% and 94.0% byCDFI and 99m^Tc-MIBI,respectively.Conclusion The combined application of CDFI and 99m^Tc-MIBI more valuable in the judgment of malignancy of cold nodules of thyroids.
