摘要
目的探讨实时剪切波弹性成像技术(SWE)在TI-RADS 4级甲状腺单发实性结节中的应用价值。方法对251例甲状腺单发实性病灶患者行SWE检查,以病理结果为金标准对其及其中112例TI-RADS 4级结节分别绘制ROC曲线,获取最佳界值E1、E2及曲线下面积ROC1、ROC2。结果 E1、E2分别为48.55kPa和52.02kPa。以E1为界值诊断TI-RADS 4级甲状腺结节,敏感性、特异性分别为75.0%、77.7%,以E2为界值诊断TI-RADS 4级结节,敏感性、特异性分别为75.0%、78.3%,二者差异无统计学意义(P>0.05)。结论对于整体甲状腺结节确定的界值亦适用于TI-RADS 4级结节,且SWE可在常规超声基础上进一步排除良、恶性病变,进一步指导临床。
Objective To evaluate the diagnostic performance of shear wave elastography（SWE）for thyroid single solid nodules.Methods 251 patients were performed of SWE examination.With the pathological results as gold standard,ROC curves were drawn to obtain the thresholds（E1,E2）and diagnoses values（ROC1,ROC2）both for 251 patients and 112 patients of TI-RADS 4within them,respectively.And the sensitivity and specificity were counted.Results The threshold value were 48.55 kPa and 52.02 kPa,respectively.Using the E1 to diagnose the nodules of TI-RADS 4,the sensitivity and specificity were 75.0% and 77.7%,respectively.Using the E2 to diagnose the nodules of TI-RADS 4,the sensitivity and specificity were 75.0%and 78.3%,respectively.And there was no significantly difference between the two sensitivities and specificities（P〉0.05）.Conclusion The threshold of all thyroid nodules was also apply to the nodules of TI-RADS 4.And SWE can significantly increase the diagnose value of thyroid nodules by combining with conventional ultrasound.
