目的 探讨非实性早期肺癌的特 征性CT表现。方法 回顾性分析临床已确 诊的76例患者83个非实性早期肺癌病灶CT 图像。结果 76例肺癌患者共83个病灶， 其中69例单发，7例多发；83个非实性早 期周围性肺癌病灶存在特征的影像表现， 病变形态为类圆形76个，不规则形7个； 分叶征62个；结节征67个；细支气管充气 征32个；细支气管截断征或局部狭窄30 个；空泡征38个；毛刺征51个；肺血管阻 挡征28个；胸膜凹陷征23个；周围肺气肿 征20个；支气管血管束征6个。结论 非实 性早期周围型肺癌的部分CT征象具有特征 性，螺旋CT检查可作为临床诊断的有效手 段。

Objective To investigate the CT features of non solid early lung cancer. Methods Methods the CT images of 83 cases of non solid early lung cancer were retrospectively analyzed in 76 patients. Results 76 cases of lung cancer patients with 83 lesions, including 69 cases of single, 7 cases of multiple; 83 non solid early peripheral lung cancer lesions are characteristic imaging features of the lesion morphology for the round of 76, 7 were irregular lobulation. 62 nodules, syndrome 67, air bronchogram 32, fine bronchus sign or local stenosis in 30. 38 spiculation, vacuole sign, 51, pulmonary vascular barrier syndrome 28, pleural indentation 23, around 20 emphysema syndrome; bronchial vascular bundle syndrome 6. Conclusion CT in solid early peripheral lung cancer like syndrome has characteristic, spiral CT examination can be used as an effective means of clinical diagnosis.
