摘　　要：目的评估电子计算机X射线断层成像(CT)薄层扫描及动态增强检查在周围型小肺癌诊断中的应用价值,以期为临床早期诊疗提供依据。方法选取焦作市疾病预防控制中心2020年3月至2022年12月期间收治的疑似周围型小肺癌患者204例作为研究对象,依据病理结果分成肺癌组(135例)与肺炎组(69例),统计对比两组CT影像特征,分析CT薄层扫描以及动态增强的诊断价值。结果肺癌组不规则形病灶、边界模糊、毛刺状边界、空泡、强化、血管侵犯占比均高于肺炎组(P<0.05);CT薄层平扫、动态增强联合诊断的敏感度、准确度均高于单一CT薄层平扫、动态增强(P<0.05);CT薄层扫描平扫、动态增强联合诊断分期结果和病理结果kappa值为0.916,高于单一检查方式(P<0.05)。结论CT薄层扫描联合动态增强检查应用于周围型小肺癌临床诊断中,具有较高诊断效能,并能为临床分期鉴别提供可参考依据,便于临床早期制定针对性治疗措施。【Objective】To evaluate the application value of thin layer scanning and dynamic enhanced examination of electronic computed tomography(CT)in the diagnosis of peripheral small lung cancer,in order to provide a basis for early clinical diagnosis and treatment.【Methods】Totally 204 suspected peripheral small lung cancer patients admitted to Jiaozuo Center for Disease Control and Prevention from March 2020 to December 2022 were selected as the research subjects.They were divided into lung cancer group(135 cases)and pneumonia group(69 cases)based on pathological results.The CT imaging characteristics of the two groups were statistically compared,and the diagnostic value of CT thin layer scanning and dynamic enhancement was analyzed.【Results】The proportion of irregular lesions,blurry boundaries,burrs,vacuoles,enhancement,and vascular invasion in the lung cancer group was significantly higher than that in the pneumonia group(P<0.05).The sensitivity and accuracy of CT thin layer plain scan and dynamic enhancement combined diagnosis were higher than those of single CT thin layer plain scan and dynamic enhancement(P<0.05).The Kappa value of the combined diagnosis and staging results of CT thin layer scanning and dynamic enhancement,as well as the pathological results,was 0.916,which was higher than that of a single examination method(P<0.05).【Conclusion】The application of CT thin layer scanning combined with dynamic contrast-enhanced examination in the clinical diagnosis of peripheral small lung cancer has high diagnostic efficacy and can provide a reference basis for clinical stage differentiation,facilitating the early development of targeted treatment measures in clinical practice.
