摘要 目的分析高频彩色多普勒超声在甲状腺乳头状癌(PTC)中的诊断效能及相关征象。方法回顾性收集经高频彩色多普勒超声诊断的41例PTC患者和46例甲状腺良性结节患者临床资料,对比PTC患者和甲状腺良性结节患者的高频彩色多普勒超声征象,分析高频彩色多普勒超声在PTC中的诊断效能及相关征象。结果高频彩色多普勒超声诊断PTC的灵敏度为90.24%(37/41)、特异度为95.65%(44/46)、准确度为93.10%(81/87)、阳性预测值为94.87%(37/39)、阴性预测值为91.67%(44/48);绘制ROC曲线显示,高频彩色多普勒超声诊断PTC的AUC为0.905(95%CI 0.872-0.993),>0.90,诊断效能较高;PTC患者中边缘不规则、无包膜、内部回声不均匀、低回声、血流丰富占比高于甲状腺良性结节患者,差异有统计学意义(P<0.05);经Logistic回归分析结果显示,高频彩色多普勒超声征象边缘不规则、无包膜、内部回声不均匀、低回声、血流丰富均与PTC有关(OR>1,P<0.05)。结论高频彩色多普勒超声在PTC中的诊断效能较高,相关征象边缘不规则、无包膜、内部回声不均匀、低回声、血流丰富均与PTC有关。
