超声弹性面积比值法与Itoh评分法鉴别诊断甲状腺结节的价值

目的探讨超声弹性面积比值法与Itoh评分法在甲状腺结节鉴别诊断中的价值。方法应用超声弹性面积比值法与Itoh评分法对23例患者31个甲状腺结节进行检查,以手术组织病理结果为金标准,比较超声弹性面积比值法与Itoh评分法诊断甲状腺结节良、恶性的准确性、特异性、敏感性。结果手术组织病理证实良性结节22个,恶性结节9个;超声弹性成像Itoh评分法诊断良性结节的符合率为63.6%（14/22）,诊断恶性结节的符合率为55.6%（5/9）;超声弹性成像面积比值法诊断良性结节的符合率为77.3%（17/22）,诊断恶性结节的符合率为77.8%（7/9）,面积比值法诊断甲状腺良性和恶性结节的符合率均高于Itoh评分法（P〈0.05）。结论超声弹性成像面积比值法在判定甲状腺结节性质上优于Itoh评分法。

Value of the sonoelastography area ratio and Itoh scoring system to the differential diagnosis of thyroid nodules

Objective To explore the value of the sonoelastography area ratio and Itoh scoring system to the differential diagnosis of thyroid nodules.Methods The sonoelastography area ratio and Itoh scoring system were used to exam 31 thyroid nodules in 23 patients,taking the histopathological results as golden standard.The accuracy,sensitivity and specificity of sonoelastography area ratio and Itoh scoring system for benign and malignant thyroid nodules were compared.Results Histopathological results confirmed 22 benign nodules and 9 malignant thyroid nodules.The coincidences of sonoelastography Itoh scoring system for benign and malignant thyroid nodules were 63.6%（14/22）and55.6%（5/9）,significantly lower than those of area ratio for benign and malignant thyroid nodules（77.3%（17/22）,77.8%（7/9））（P〈0.05）.Conclusion Sonoelastography area ratio method is superior to Itoh scoring system in the differentiate diagnosis of benign and malignant thyroid nodules.
