摘　　要：【目的】探讨超声弹性成像在甲状腺癌鉴别诊断中的作用。【方法】收集2013年1月至2015年1月期间我院手术的甲状腺结节性疾病患者244例,依据术后病理检查结果,分为良性结节组及恶性结节组,采用超声弹性图像评分5分法计算,对比分析,分析超声弹性成像鉴别甲状腺癌的敏感性及特异性,绘制ROC曲线,界定诊断界点。【结果】ROC曲线下面积0.88,标准误为0.03(P<0.001),说明超声弹性成像在甲状腺癌鉴别诊断中有显著性意义。【结论】超声弹性成像是鉴别甲状腺癌较为有效的检查的方法。[Objective] To explore the role of ultrasound elastography in differential diagnosis of thyroid cancer. [Methods] From January 2013 to January 2015, 244 surgical patients diagnosed as thyroid nodular disease in our hospital were selected in the study. According to the postoperative pathological results, they were divided into two groups： benign-nodule group and malignant-nodule group. We analyzed the sensitivity and specificity of ultrasound elastography in diagnosing thyroid cancer by 5-point-evaluation of ultrasound elasticity imaging. ROC curve was drawn to define the critical point of diagnosis. [ Results] The ROC curve showed an area of 0.88 and a standard error of 0.03 （P〈0.001）. It indicated that ultrasound elastograhy was significant in diagnosing thyroid cancer. [ Conclusion ] Ultrasound elastography is an effective method in differential diagnosis of thyroid cancer.
