Abstract］ objective to study the knowledge of the imaging manifestation of x-ray and ct in peripheral small lung cancer.methods to collect twenty cases with no symptom in early time diagnosed by clinic and to retrospectively analyze their imaging features.results x-ray appeared patch,small node.ct appeared patch,small node,light lobulation,peripheral vessel convergence,pleural indentation sign.most of the diameter was 1.5 to 2 cm,with no mediastinum and pulmonary hilar lymph nodes diversion.furthermore the clinical symptom was not obviously.conclusion to be familiar and handling the sign mentioned above is the key to boost the diagnosis of small peripheral lung cancer.

目的 探讨周围型小肺癌的x线、ct影像学表现。方法收集临床和病理证实的早期无症状肺癌20例，对其影像学进行回顾分析。结果本组早期肺癌x线为斑片状、小结节状。ct表现为斑片状、小结节状、轻度分叶状肿块，小毛刺、血管集束征、胸膜凹陷征，大多直径在1.5～2 cm。无纵隔淋巴及肺门转移，且临床症状不明显。结论熟悉并掌握上述征象是提高小肺癌早期诊断率的关键。
