    Comparison of the diagnostic efficacy of different methods measuring ultrasonicity elastic contrast index in the diagnosis of thyroid nodule

      摘要
    • 摘要:
      目的探讨超声弹性对比指数（elasticity contrast index，ECI）在诊断甲状腺结节中的应用价值，同时比较不同测量方法的效能。
      方法选取甲状腺结节病人31例共36个结节，分别以勾勒横切面结节边界、横切面结节内不均质区、纵切面结节边界3种方法测量ECI，绘制受试者工作特征（ROC）曲线，比较不同测量方法对甲状腺结节的诊断效能。
      结果3种方法中，横切面结节内不均质区测量法ROC曲线下面积最大，为0.82，对应ECI界值2.93，其评价甲状腺结节恶性风险的敏感性、特异性、准确性分别为82.0%、76.4%、75.3%，以横切面结节内不均质区法测定，恶性结节的ECI值高于良性结节（P < 0.05）。
      结论横切面结节内不均质区测量ECI法对甲状腺结节有较高的诊断效能。

       

      Abstract:
      ObjectiveTo explore the application value of ultrasonic elasticity contrast index(ECI) in the diagnosis of thyroid nodules, and compare the efficacy among different measurement methods.
      MethodsA total of 31 patients with thyroid nodules(36 nodules) were investigated, and the ECI was measured using the sketching the cross-sectional junction boundary, measurement of inhomogeneous areas within nodules in cross section and cross-sectional junction boundary, respectively.The ROC curve was drawn, and the diagnostic effects of thyroid nodules were compared among different measurement methods.
      ResultsAmong the three methods, the area under the ROC curve of the measurement of inhomogeneous areas within nodules in cross section was the largest(0.82), and the corresponding ECI cut-off value was 2.93.The sensitivity, specificity and accuracy of the measurement of inhomogeneous areas within nodules in cross section in evaluating the malignant risk of thyroid nodules were 82.0%, 76.4% and 75.3%, respectively.Using the measurement of inhomogeneous areas within nodules in cross section, the ECI value of malignant nodules is high than that of benign nodules (P < 0.05).
      ConclusionsThe measurement of inhomogeneous areas within nodules in cross section has a high diagnostic effect on thyroid nodules.
