摘　　要：目的:探讨甲状腺癌颈部转移性和非转移性淋巴结的超声特征。方法:选取笔者所在医院(2015年1月-2016年12月)收治的50例甲状腺癌患者为研究对象,本组患者在术前均接受颈部超声检查,经颈部超声检查发现有130枚颈部淋巴结,手术病理证实其中有非转移性淋巴结62枚,转移性淋巴结68枚,比较超声影像特征。结果:超声诊断的阴性预测值为68.67%(57/83),阳性预测值为89.36%(42/47),特异度为91.94%(57/62),灵敏度为61.76%(42/68)。灰阶超声诊断显示,转移组和非转移组回声均质性、内部回声、内部结构、晕圈、边缘、边界对差异均无统计学意义(P>0.05)。转移组和非转移组淋巴结大小、钙化、血流丰富程度对比差异有统计学意义(P<0.05)。转移组和非转移组PSV、PI对比差异无统计学意义(P>0.05);而转移组RI明显高于非转移组,差异有统计学意义(P<0.05)。结论:甲状腺癌颈部转移性淋巴结有一定的超声特征,可以通过多个指标判断来提高对甲状腺癌颈部转移性淋巴结的检出率。Objective:To investigate the ultrasonographic characteristics of metastatic and non metastatic lymph nodes in the neck of thyroid carcinoma.Method:In our hospital(from January 2015 to December 2016)50 patients with thyroid cancer were selected as research objects,this group of patients undergoing neck ultrasound examination before operation.The neck ultrasound examination revealed 130 cervical lymph node pathology,including 62 non metastatic lymph nodes,68 metastatic lymph nodes.Result:The negative predictive value of ultrasound diagnosis was 68.67%(57/83),the positive predictive value was 89.36%(42/47),the specificity was 91.94%(57/62),and the sensitivity was 61.76%(42/68).Gray scale ultrasound diagnosis showed that there was no significant difference in echo homogeneity,nternal echo,internal structure,halo,border and border contrast between metastatic group and non metastatic group,with no statistical significance(P>0.05).There were significant differences in the size,calcification and blood flow richness of the lymph nodes in the metastatic group and the non metastasis group,which was statistically significant(P<0.05).There was no significant difference in PSV and PI between metastatic group and non metastatic group,with no statistically significant(P>0.05),while RI in metastatic group was significantly higher than that in non metastasis group(P<0.05).Conclusion:The metastatic lymph nodes of thyroid cancer have certain ultrasonographic characteristics,and multiple indicators can be used to improve the detection rate of metastatic lymph nodes in the neck of thyroid cancer.
