| 目的 通过分别比较结合弹性成像评分法的改良甲状腺影像学报告及数据系统(TI-RADS)评分法和超声弹性成像的半定量分析即弹性应变率比值与甲状腺结节良恶性的相关性,获到更好的甲状腺结节定性方式。方法 回顾性分析经病理证实的86例(118个结节)的超声诊断报告,对结合弹性成像的改良 TI-RADS评分法和应变率比值进行良恶性组间比较,并对有统计学差别的量化指标构建受试者操作特征(ROC)曲线,计算曲线下面积,判断其诊断价值。结果 改良 TI-RADS评分法和应变率比值的良恶性组间差别均有统计学意义(P<0.05)。绘制ROC曲线,曲线下面积分别为0.784和0.919,诊断临界值分别为5分和3.3,约登指数分别为0.526和0.871,其敏感度、特异度分别为65.22%、87.37%和91.30%、96.84%,Kappa值分别为0.493和0.867。结论 超声弹性成像半定量分析更有助于甲状腺良恶性结节的诊断。 |

| Objective To explore the feasibility for TI-RADS combined with elasticity score and the semi-quantitative analysis of ultrasound elastography in diagnosing benign or malignant of thyroid lesions. Methods Eighty-six patients with 118 lesions were retrospectively analyzed.The receiver operating characteristic curve(ROC) was constructed if there were statistically significant differences between benign and malignant lesions,and the areas under the ROC curve were arrived. Results All parameters had statistically significant differences between the groups of benign and malignant thyroid lesions(P<0.05).The areas under the curve(AUC) of which were 0.784 and 0.919,respectively.Their cut-off points were score 5 and 3.3,Youden indexes were 0.526 and 0.871,the sensitivity and specificity were 65.22%,87.37% and 91.30%,96.84%,Kappa values were 0.493 and 0.867. Conclusion Semi-quantitative analysis of ultrasound elastography contributes to the diagnosis of benign and malignant thyroid nodules. |
