[摘要] 目的：探讨周围型支气管肺癌早期的影像诊断。方法：收集经手术病理证实为周围型支气管肺癌≤3 cm肺内孤立性结节32例，全部病例先摄X线胸片再做CT扫描，对<2 cm结节再做薄层扫描。结果：下列征象对恶性病变诊断有帮助：结节边缘分叶、棘状突起和毛刺征，空泡征，肺结节并肺门淋巴肿大。结论：通过对肺内孤立性结节恶性病例常规X线胸片与CT进行分析探讨，可以达到优势互补，以提高对本病例的认识、了解。

    [Abstract] Objective:To discuss the early phantom diagnostic of the peripheral lung cancer.Methods:We collected 32 peripheral lung cancers that approved isolation tubercle less than 3 centimetres after surgery and pathology,all of the cases absorbed X-ray at first ,then CT scaning. We made the thin layer scanning again to the tubercle less than 2 centimetres.Results: The following signs were helpful to diagnose the m alignant pathological:the tubercle edge sublobe,the thorn slape of protuberance and burrsign,the dacuole sign,the lung tubercle and the lung hilus, lymphare tumescent.Conclusion:Through analyzing and discussing the isolated tubercle m alignant case that made X-ray sternum and CT,we canunderstand this case better. ......
