Objective :To assess the overall value of lobulation sign and deep lobulation sign in the differential diagnosis of peripheral lung cancer and pulmonary tuberculoma in CT images.Methods : Firstly , articles about CT differential diagnosis between pulmonary tuberculoma and peripheral lung cancer were selected ,which were published in the period(from January 1990 to December 2008),and useful data were extracted.Then Meta-analysis was done using Meta-disc software,and SDOR value calculated.

方法搜集1990年1月至2008年12月国内外公然发表的关于四周型肺癌与肺结核球CT鉴别诊断的文献，对文献进行筛选，应用Meta-disc软件对符合条件的原始研究进行质量评估、异质性检验，计算阳性似然比、阴性似然比和诊断比值比，最后汇总敏感性和特异性，绘制SROC曲线并计算曲线下面积来综合评价分叶征及深分叶征在CT检查中对于四周型肺癌与结核球鉴别诊断的价值，进行敏感性和特异性分析。
