摘　　要：目的:探讨早期肺癌的CT影像学特征,提高早期肺癌的诊断能力及筛查率。方法:通过回顾性分析我院近5年病理证实的127例早期肺癌患者CT数据,掌握早期肺癌的CT影像学特征,并分析危险因素对早期肺癌误诊率的相关性。结果:本资料127例早期肺癌CT数据中,周围型肺癌误诊率为7.2%、中央型肺癌误诊率为13.3%,其差异性不具有统计学意义(P>0.05);结节的直径大小的差异在早期周围型肺癌的诊断率中具有统计学意义(P<0.05),小于1 cm的结节容易漏诊;肺门影的差异在早期中央型肺癌的诊断率中具有统计学意义(P<0.05),肺门影不大的结节容易被漏诊。结论:早期肺癌的CT表现具有一定的特征性,直径小于1 cm的结节或肺门影不大时容易漏诊,需要密切随访。Objective： To explore the CT imaging features of early lung cancer, so as to improve its diagnosis. Methods： The CT imaging findings of 127 cases of patients with early lung cancer were retrospectively studied and mastered. The correlation between the risk factors and the rate of early misdiagnosis was analyzed. Results：Images of 127 cases with early lung cancer were studied. The misdiagnosis rate of peripheral lung cancer and central lung cancer was 7.2% and 13.3% respectively. The differences were not statistically significantly （P 〉 0.05 ）. The difference of nodule size was statistically significant with early peripheral lung cancer, and the size of nodules smaller than lcm was easily to be missed in diagnosis （ P 〈 0.05 ）. The difference of hilar shadow was statistically significant with early central lung cancer, and nodules with smaller hilar shadow were more likely to be missed （P 〈 0.05 ）. Conclusion：The early lung cancer CT scanning has some significant features. Nodules smaller than 1 cm in size with not big enough hilar shadow were more easily to be missed. So these cancer cases need close follow-up.
