【摘要】:目的: 建立以甲状腺微小结节超声诊断特征为变量的Logistic回归模型,评价二维灰阶超声、彩色多普勒超声、超声弹性成像及超声造影成像模式在甲状腺微小实性结节中的诊断价值。 方法: 回顾性分析经手术病理证实的130例共142个最大直径≤1.0cm的病灶且无甲状腺弥漫性病变患者的临床资料,142个病灶中,其中良性68个,恶性74个,对结节各项超声诊断指标采用多因素回归分析方法,建立Logistic回归模型,绘制ROC曲线并计算曲线下面积。 结果: Logistic逐步回归分析显示结节内部微钙化,纵横比,造影晚期回声及弹性评分4个变量进入回归模型,该Logistic回归模型对最大直径≤1.0cm的甲状腺结节良恶性预报的正确率为92.1%(129/142),ROC曲线下面积为0.944。 结论: 二维和彩色多普勒超声结合组织弹性成像技术及实时超声造影技术在最大直径≤1.0cm的甲状腺良恶性结节的鉴别诊断中具有较高的临床应用价值。
