2、膜的关系、内部回声、钙化类型、周边回声特征及后方回声。将上述灰阶超声表现与颈部淋巴结转移行单因素分析和多因素回归分析(Logistic回归)，研究两者的关系。结果：PTMC与颈部淋巴结转移有相关性的超声表现是癌结节大小、结节与甲状腺被膜的关系、癌结节内部的钙化类型(P

3、结论：PTMC的大小、与甲状腺被膜关系、内部钙化类型等灰阶超声表现，可提示PTMC发生颈部淋巴结转移的可能性，两者之间存在相关关系。[关键词]甲状腺肿瘤；淋巴转移；超声检查；Logistic模型Predictionofcervicallymphnodemetastasisofpapillarythyroidmicrocarcinomawithgray-scaleultrasoundX【，Li—yun，L儿，Cui—xia．ChangpingHospitalofTCMinPeking，Peking
