2、systolicvelocity,PSV)、RI,并与4O枚反应增生性淋巴结对比。结果:转移淋巴结长短径比值较小、边界欠清、皮质增厚、淋巴门高回声消失、内部可见囊性变及钙化、Adler血流分级及PSV均较高,与反应增生性淋巴结相比差异有统计学意义。结论:甲状腺癌颈部淋巴结转移具有特征性超声表现,其准确诊断及定位有助于指导患者的治疗。[关键词]甲状腺肿瘤;淋巴转移;前哨淋巴结组织检查;超声检查Theultrasonographicmanifestationsofmetastaticcervicallymphnodesinthyroidcarcinomaandevaluationofitscli
