目的探讨螺旋CT对周边型小肺癌的诊断价值。方法对46例经手术病理证实的具有完整资料的周边型小肺癌CT征象进行回顾性分析。结果46例周边型小肺癌中,具有深分叶征22例,浅分叶13例,细小毛刺19例,小泡征11例,空气支气管征5例,血管集束征26例,胸膜凹陷征13例。34例做了增强扫描,增强幅度在20～55Hu之间。结论根据周边型小肺癌病灶的内部结构、边缘特征、增强幅度以及病灶与周围结构的关系,可提高CT诊断准确率。
Objective To investigate the diagnostic value of spiral CT in peripheral small lung cancer. Methods A retrospective analysis of CT findings of 46 cases of peripheral small lung cancer with complete data confirmed by surgery and pathology was performed. Results Among the 46 patients with peripheral small lung cancer, there were 22 cases of deep lobulation, 13 cases of shallow lobulation, 19 cases of small burr, 11 cases of vesicle sign, 5 cases of air bronchus sign, 26 cases of vascular bundle sign and 13 cases of pleural indentation example. 34 cases made enhanced scan, the enhancement range between 20 ~ 55Hu. Conclusion The accuracy of CT diagnosis can be improved according to the internal structure, marginal features, the extent of enhancement, and the relationship between the lesions and the surrounding structures in peripheral small lung cancer.
