[摘要] 目的 探讨高分辨薄层CT用于早期肺腺癌诊断筛查中的效果。方法 方便选择2017年1月—2019年8月經该院病理学确诊治疗的早期肺腺癌患者70例作为对象，随机数字表分为对照组（n=35）和观察组（n=35）。对照组给予常规CT检查，观察组给予高分辨薄层CT检查，比较两组不同CT扫描方式下肿瘤征象显示率，图像质量以及诊出率。结果 观察组中棘突征检出率为85.71%，对照组为57.14%（χ2=6.396）、观察组中毛刺征为71.43%，对照组为51.43%（χ2=5.786）、观察组中钙化征为45.71%，对照组为11.43%（χ2=4.935）、观察组中血管集束征为74.29%，对照组为48.57%（χ2=7.972）、观察组中分叶征为85.71%，对照组为60.00%（χ2=4.997）、观察组中空泡征为28.57%，对照组为8.57%（χ2=8.016）、观察组中胸膜凹陷征为77.14%，对照组为45.71%（χ2=6.472）。观察组中对于棘突征、毛刺征、钙化征、血管集束征、分叶征、空泡征、胸膜凹陷征等显示率均高于对照组（P<0.05）。观察组的图像总优良率为94.28%，对照组的总优良率为77.14%，观察组的图像总优良率明显高于对照组（χ2=7.371，P<0.05）;参照病理学检测结果，观察组的诊出率为97.14%，对照组的诊出率为71.43%，观察组的诊出率明显高于对照组（χ2=6.827，P<0.05）。结论 将高分辨薄层CT用于早期肺腺癌诊断筛查中，可以清晰看到肿瘤，病灶区内部结构等特征，提高CT的成像质量，提高诊出率。

[Abstract] Objective To explore the effect of high-resolution thin-layer CT in the diagnosis and screening of early lung adenocarcinoma. Methods Seventy patients with early-stage lung adenocarcinoma diagnosed and treated by the pathology of the hospital from January 2017 to August 2019 were convenient selected as subjects. The random number table was divided into the control group （n=35） and the observation group （n=35）. The control group was given conventional CT examination， and the observation group was given high-resolution thin-layer CT examination. The tumor sign display rate， image quality， and diagnosis rate were compared between the two groups under different CT scans. Results The detection rate of spinous process in the observation group was 85.71%， 57.14% in the control group （χ2=6.396）， the glitch sign in the observation group was 71.43%， the control group was 51.43%（χ2=5.786）， and the calcification in the observation group was 45.71%， the control group was 11.43%（χ2=4.935）， the vascular bundle sign in the observation group was 74.29%， the control group was 48.57%（χ2=7.972）， the leaf splitting sign in the observation group was 85.71%， and the control group was 60.00%（χ2=4.997）， the hollow sign in the observation group was 28.57%， in the control group was 8.57%（χ2=8.016）， in the observation group， the pleural depression was 77.14%， and the control group was 45.71%（χ2= 6.472）. In the observation group， the display rates of spinous process sign， glitch sign， calcification sign， vascular bundle sign， defoliation sign， vacuole sign， and pleural depression sign were all higher than those in the control group（P<0.05）. The overall excellent and good rate of the observation group was 94.28%， and the total excellent and good rate of the control group was 77.14%. The overall excellent and good rate of the observation group was significantly higher than that of the control group（χ2=7.371， P<0.05）. The diagnosis rate in the group was 97.14%， and that in the control group was 71.43%. The diagnosis rate in the observation group was significantly higher than that in the control group（χ2=6.827， P<0.05）. Conclusion The use of high-resolution thin-layer CT in the early diagnosis of lung adenocarcinoma can clearly see the characteristics of the tumor and the internal structure of the lesion area， improve the imaging quality of CT， and improve the diagnosis rate.
