[摘要] 目的 研究CT对肺癌脑转移瘤的诊断价值。方法 收集30例确诊为肺癌行常规CT检查发现脑部肿瘤的患者资料进行分析。结果 30例患者中，脑转移瘤多发23例，单发7例。转移瘤大小为12～50 mm。幕上26例，其中21例位于皮层及皮层下，5例紧贴颅骨；幕下4例。平扫呈低密度15例，等密度11例，高密度4例；增强后，结节型10例，环状型11例，环状与结节状增强同时存在的混合型5例，不规则型4例。原发瘤组织类型中腺癌17例，鳞癌4例，其他类型9例。结论 CT平扫及增强扫描对于肺癌脑转移的诊断极有价值，且脑部CT扫描发现病灶，进行胸部排癌检查极有必要。[关键词] 肺肿瘤；脑转移瘤；体层摄影术，X线计算机

[Abstract] Objective To assess the value of detection of brain metastasis in lung cancer by CT.Methods We studied 30 patients,who were detected by CT with brain metastasis in lung cancer.Results Of 30 cases,7 were single metastasis,and 23 were multiple metastases.The size of brain tumors was 12～50 mm.The main location of brain metastasis were in cortex and hypophloeodal layer.15 cases were hypodense,and 11 were isodense,4 hyperdense by plain CT scanning.When scanned with enhanced CT,10 cases were nodulated,11 annular and 5 were mixed,and 4 were irregular.By the histology of lung cancer,17 were adenocarcinoma,4 squamous cell and 9 were others.Conclusion The application of plain and enhanced CT scanning is helpful for the diagnosis of brain metastasis in lung cancer,and if there were brain metastases by CT,the detection of chest should be taken for exclusion the possibility of lung cancer. ......
