多排螺旋CT技术鉴别诊断早期周围型小肺癌的效果

The effect of multi-slice spiral CT in the differential diagnosis of early peripheral small lung cancer

目的:探究多排螺旋CT技术诊断早期周围型小肺癌的效果。方法:2018年6月-2020年3月收治疑似早期周围型小肺癌患者200例,所有患者均经病理检查,其中阳性186例,阴性14例。采用多排螺旋CT对所有患者进行检查,将病理检查结果作为金标准,比较多排螺旋CT检查的效果。结果:CT检查阴性15例,阳性185例,准确度为97.5%,灵敏度为98.3%,特异度为85.7%。经过CT检查发现,病灶位于右肺上叶部位44例,右肺中叶部位35例,右肺下叶部位23例,左肺上叶部位56例,左肺下叶部位27例。结论:针对早期周围型小肺癌患者实施多排螺旋CT检查效果显著,能够准确诊断和鉴别。

Objective:To explore the effect of multi-slice spiral CT in the diagnosis of early peripheral small lung cancer.Methods:From June 2018 to March 2020,200 cases of patients with suspected early peripheral lung cancer were enrolled,all patients underwent pathological examinations,among them,186 cases were positive and 14 cases were negative.Multi-slice spiral CT was used to examine all patients,while pathological examination results were used as the gold standard to compare the effects of multi-slice spiral CT.Results:15 cases of CT examination were negative and 185 cases were positive.The accuracy was 97.5%,the sensitivity was 98.3%and the specificity was 85.7%.After CT examination,44 cases were found in the upper lobe of the right lung,35 cases were in the middle lobe of the right lung,23 cases were in the lower lobe of the right lung,56 cases were in the upper lobe of the left lung and 27 cases were in the lower lobe of the left lung.Conclusion:Multi-slice spiral CT examination for patients with early peripheral small lung cancer has a significant effect and it can accurately diagnose and differentiate early peripheral small lung cancer.
