摘　　要：目的:探讨高分辨率CT就肺小结节及早期肺癌患者的临床诊断价值。方法:收集2017年3月~2019年3月本院孤立性肺小结节的患者,所有患者均有手术病理或穿刺病理结果,根据病理结果分为:肺癌组和良性组。分析肺癌组和良性组病理结果;对比两组结节大小、结节生长部位、边缘形态及内部特征。结果:肺癌组孤立性肺小结节直径2.1~2.9cm,平均(2.26±0.61)cm,良性组孤立性肺小结节直径2.2~3.1cm,平均(2.29±0.75)cm,两组结果比较无差异(P>0.05);肺癌组和良性组结节生长部位结果比较无差异(P>0.05);肺癌组结节边缘形态及内部特征(钙化、毛刺、分叶、棘状突起、空泡征)发生率高于良性组,两组结果比较有差异(P<0.05);肺癌组结节边缘形态及内部特征(钙化、毛刺、分叶、棘状突起、空泡征)发生率高于良性组,两组结果比较有差异(P<0.05)。结论:通过高分辨率CT检查,可以明确发现恶性肺癌孤立性肺小结节边缘形态及内部特征与良性孤立性肺小结节存在差异,具体体现在钙化、毛刺、分叶、棘状突起及空泡征。Objective:To explore the clinical value of high-resolution CT in the diagnosis of pulmonary nodules and early lung cancer.Methods:Patients with solitary pulmonary nodules in our hospital were collected.All patients had surgical or puncture pathological results.According to the pathological results,they were divided into lung cancer group and benign group.Pathological results of lung cancer group and benign group were analyzed.The size,growth site,peripheral morphology and internal characteristics of nodules in the two groups were compared.Results:The diameter of solitary pulmonary nodules in the lung cancer group was 2.1~2.9 cm,with an average diameter of(2.26±0.61)cm;the diameter of solitary pulmonary nodules in the benign group was 2.2~3.1 cm,with an average diameter of(2.29±0.75)cm;there was no difference between the two groups(P>0.05).There was no difference in nodule growth site between the lung cancer group and the benign group(P>,0.05).The incidence of peripheral morphology and internal characteristics of nodules(calcification,burr,lobulation,spinous protrusion,cavitation)in the lung cancer group was higher than that in the control group(P<0.05).The incidence of peripheral morphology and internal characteristics(calcification,burr,lobulation,spines,cavitation)of nodules in the lung cancer group was higher than that in the control group,and the results were different between the two groups(P<0.05).Conclusion:High resolution CT examination can clearly find that there are differences between the marginal morphology and internal characteristics of solitary pulmonary nodules in malignant lung cancer and benign solitary pulmonary nodules,which are embodied in calcification,burr,lobulation,spines and cavitation.
