摘　　要：目的:探讨超声在甲状腺乳头状癌颈部淋巴结转移诊断中的临床价值。方法:选择2013年1月-2015年12月在我院诊断治疗的甲状腺乳头状癌伴颈部淋巴结肿大的患者262例的临床资料进行回顾性分析。所有患者在术前行超声检查,分析超声影像学指标在诊断甲状腺乳头状癌颈部淋巴结方面的敏感性、特异性、准确度、阳性预测值、阴性预测值。结果:超声诊断结果与病理诊断结果比较:χ~2=1.917,P>0.05,敏感性为78.1%,特异性为97.9%,准确度为81.7%,阳性预测值为99.4%,阴性预测值为49.5%。淋巴结转移组纵横比<2、内部回声不均匀率、边界不规则率、钙化率、有血流信号率显著高于未转移组(P<0.01)。结论:超声诊断甲状腺乳头状癌颈部淋巴结转移具有较高的敏感性、特异性、准确度,有利于术前的辅助诊断,指导治疗。Objective:To discuss clinical value of ultrasonography in diagnosing cervical lymph node metastasis after papillary thyroid carcinoma.Methods:Clinical data of262cases from Jan.2013to Dec.2015were respectively analyzed.All patients were examined by ultrasonography before operation.Results:Comparison of the results of ultrasound diagnosis and pathologic diagnosis showed significant difference(χ2=1.917,P>0.05);and sensitivity was78.1%;specificity was97.9%;accuracy was81.7%;positive predictive value was99.4%;negative predictive value was49.5%.Aspect ratio<2;internal echo non-uniformity rate,irregular boundary,calcification rate,blood flow signal rate in the lymph node metastasis group were higher than those in the non-transfer group(P<0.01).Conclusion:Ultrasonography in diagnosing cervical lymph node metastasis after papillary thyroid carcinoma is with high sensitivity,specificity,accuracy,which is conducive to preoperative diagnosis and guide treatment.
