目的探讨实时组织弹性成像在甲状腺良恶性结节鉴别诊断中的应用价值.方法术前采用超声弹性成像技术对273例(500个结节)患者的甲状腺结节进行常规超声检查，并予以弹性成像分级.结果结节性甲状腺肿、腺瘤、亚急性甲状腺炎、淋巴性甲状腺炎等弹性分级以≤Ⅱ级为主，甲状腺癌弹性分级以≥Ⅲ级为主.良性结节的弹性分级以0~Ⅱ级为主，恶性结节的弹性分级以Ⅲ~Ⅳ级为主，甲状腺良恶性结节弹性分级，差异有统计学意义(P<0.05).弹性分级Ⅲ级时，良恶性结节差异比较有统计学意义(P<0.05).对于甲状腺结节良恶性的鉴别，超声弹性分级诊断的敏感度、特异度和准确率分别为86.2%、92.9%、91.6%.阳性预测值、阴性预测值分别为73.6%、96.7%.结论实时组织弹性成像对鉴别甲状腺结节的良恶性有重要的应用价值.

Objective To evaluate the application value of real time tissue elastography(RTE) in differential diagnosis of benignand malignant thyroid nodules.Methods Ultrasonic elasticity imaging were used to examine 500 thyroid nodules accordingto the strain grade in comparison with pathology.Results The majority of the elasticity grade in nodular goiter,adenoma nodules,subacute thyroiditis flexibility covered grade≤II,while papillary thyroid carcinoma covered grade≥Ⅲ.The majority of the elasticity grade in benign nodules covered grade 0~II,while malignant nodules covered grade Ⅲ~Ⅳ.The elasticity grades were statistically different between benign and malignant lesions(P<0.05).At grade ill, statisticall difference was found between benign and malignant lesions(P<0.05).The sensitivity,specificity, accuracy rate of RTE was 86.2%, 92.9%and 91.6%,respectively.Positive predictive value, negative predictive value were 73.6%, 96.7%, respectively. Conclusion RTE in differentiating benign and malignant thyroid nodules has important application value.
