【摘要】 目的 :探讨最能反映转移性颈淋巴结肿大的超声指标。方法 :回顾性分析已经病理证实的 2 10个肿大颈淋巴结的超声表现。分别用单因素和多因素逻辑回归分析判断每个超声检测指标的诊断价值。结果 :单因素逻辑回归分析显示所有超声检测指标均可单独用来评价颈淋巴结肿大是否来源于肿瘤转移 ,而多因素逻辑回归分析显示只有 3种超声表现对于鉴别转移性和非转移性有统计学意义 ,其中淋巴结横径增加、内部回声不均匀预示颈淋巴结转移[优势比 (Odds Ratio) OR<1],淋巴门有血流预示非转移性淋巴结肿大 (OR>1)。结论 :淋巴结横径增大、内部回声不均和有否淋巴门血流是判断颈淋巴结是否转移的主要超声诊断指标更多还原

【Abstract】 Objective:To find which sonographic features to be good indicators for metastatic cervical lymph nodes.Methods:Two hundred and ten cervical lymph nodes were assessed retrospectively with univariate and multivariate logistic regression analyses.Results:At univariate analysis,all sonographic features assessed were found to be important.As multivariate analysis,however,it suggested that the heterogeneous internal echo and increases of short axis length were predictive for metastatic nodes,and presence of hilar flow was predictive for reactive lymph nodes.Conclusions:Increasing in short axis length,heterogeneous internal echo and presence of hilar flow were most predictive for metastatic or cervical reactive lymph nodes in the sonographic criteria assessed by logistic regression analysis.更多还原
