摘　　要：目的:分析比较小细胞肺癌及非小细胞肺癌脑转移瘤在磁共振弥散加权序列中的特征,并结合相关文献进行分析,旨在进一步提高小细胞肺癌脑转移瘤诊断正确率,为临床治疗提供可靠依据。方法:回顾性分析30例小细胞肺癌及26例非小细胞肺癌脑转移瘤磁共振常规平扫、弥散加权成像影像特征,并对瘤周水肿、弥散表观系数值、相对扩散系数值结果进行统计学分析。结果:小细胞肺癌脑转移瘤周水肿轻微或无水肿,弥散加权序列呈现高信号,弥散表观系数值及相对扩散系数值低于非小细胞肺癌脑转移瘤。结论:小细胞肺癌脑转移瘤在弥散加权成像中具有重要特征,正确认识可以提高小细胞肺癌脑转移瘤诊断正确率。Objective：To analysis and comparison of characteristi cs in diffusion weighted imaging of brain metastatic tumor from small cell lung cancer and non-small cell lung cancer,and combined with related literature to carry on the analysis,aims to further improve the diagnosis accuracy in brain m etastatic tumor from small cell lung cancer,and provide reliable basis for clin ical treatment.Methods：Retrospective analysis of 30 patients with brain metastt ic tumor from small cell lung cancer and 26 cases of non-small cell lung cancer.MR routine scan,diffusion weighted imaging characteristics,can and the tumor weeks edema,apparent diffusion coefficients value,relatively apparent diffusio n coefficients value for the statistical analysis of the results.Results：Week o f brain metastatic tumor from small cell lung cancer edema,slight or no edema, diffusion weighted imaging sequence can show high signal,apparent diffusion coe fficients values and the relatively apparent diffusion coefficients value below the non-small cell lung cancer brain metastases.Conclusion：Brain metastatic tu mor from small cell lung cancer in diffusion weighted imaging can has important characteristic,correct understanding can improve the brain metastatic tumor fro m small cell lung cancer diagnosis accuracy.
