摘　　要：目的:探讨直径≤1.5cm的周围型微小肺癌的CT表现。方法:对CT、临床资料完整,经病理证实的17例微小肺癌的CT表现,作一回顾性分析。结果:在17个结节的分析中,见分叶征11,小泡征7,空气支气管征4,毛刺9,血管集束征8,胸膜凹陷9,磨砂玻璃影7。12个结节具有2种以上CT征象。在40天的CT随访观察中,结节的大小均无改变。结论:周围型肺小结节如存在上述2种以上CT征象、磨砂玻璃征、40天内CT复查结节无吸收缩小者,应高度怀疑肺癌的可能性。Objective：To present CT finding of small peripheral lung cancer. Methods： Seventeen patients with small （ ≤1.5cm）peripheral lung nodules were included in this retrospective study.All patients underwent CT scans and surgery. Lung cancer were confirmed by histopathology in all cases, Results： On qualitative analysis of the 17 nodules, the characteristic CT findings showed lobulation in 11 cases. vacuole sign in 7 cases ,air brochogram in 4 cases,vessel convergence in 8 cases, spiculation in 9 cases, pleural tag in 9 cases, pure or part solid ground opacity in 7 cases. On quantitative analysis, is there was no notable changes in size and shape of these nodules in follow-up CT examination after 40 days, Conclusion： With the presence of two or more above-mentioned CT signs within one nodule. ground glass opacity and no remarkable resolution of the nodule after 40 days observation, a small lung cancer should be strongly suspected.
