摘　　要：目的研究高分辨计算机断层扫描(CT)对早期肺癌的诊断效能。方法选取2018年1月至2020年12月在本院检查出肺结节的267例患者,均进行高分辨CT检查。以病理检查结果为金标准,分析高分辨CT对早期肺癌的诊断结果;根据病理检查结果将患者分为良性肺结节组和早期肺癌组,比较两组的CT征象以及CT灌注参数;分析高分辨CT的图像质量。结果病理检查结果显示,267例患者中共有良性肺结节210例,早期肺癌57例;高分辨CT检查显示,良性肺结节212例,早期肺癌55例;高分辨CT诊断早期肺癌的灵敏度、特异度、准确度、误诊率、漏诊率、阳性预测值、阴性预测值分别为94.74%、99.52%、98.50%、0.48%、5.26%、98.18%、98.58%。早期肺癌组的深分叶征、细小毛刺征、支气管截断征、血管集束征、胸膜牵拉征、钙化、空洞征检出率均高于良性肺结节组(P<0.05)。早期肺癌组的血容量、血流量、表面渗透性高于良性肺结节组,平均通过时间短于良性肺结节组(P<0.05)。267例患者中,高分辨CT图像质量为优的占89.14%,为良的占10.86%,优良率为100%。结论高分辨CT在筛查肺结节时对早期肺癌具有较高的诊断效能。Objective To study the diagnostic efficacy of high-resolution computed tomography(CT)for early lung cancer.Methods From January 2018 to December 2020,267 patients with pulmonary nodules examined in our hospital were selected,and all underwent high-resolution CT examination.Taking results of pathological examination as gold standard,the diagnostic results of high-resolution CT for early lung cancer was analyzed;the patients were divided into benign pulmonary nodules group and early lung cancer group according to pathological examination results,and CT signs and CT perfusion parameters of the two groups were compared;the image quality of high-resolution CT was analyzed.Results The results of pathological examination showed that 210 cases of benign pulmonary nodules and 57 cases of early lung cancer were found in 267 patients;high-resolution CT showed 212 cases of benign pulmonary nodules and 55 cases of early lung cancer;the sensitivity,specificity,accuracy,misdiagnosis rate,missed diagnosis rate,positive predictive value,negative predictive value of high-resolution CT in the diagnosis of early lung cancer were 94.74%,99.52%,98.50%,0.48%,5.26%,98.18%,98.58%,respectively.The detection rates of deep lobulation sign,small burr sign,bronchial truncation sign,vascular convergence sign,pleural traction sign,calcification and cavity sign in the early lung cancer group were higher than those in the benign pulmonary nodules group(P<0.05).The blood volume,blood flow and surface permeability in the early lung cancer group were higher than those in the benign pulmonary nodules group,and the mean transit time was shorter than that of the benign pulmonary nodules group(P<0.05).Among the 267 patients,the high-resolution CT image quality was excellent accounting for 89.14%,good accounting for 10.86%,and the excellent and good rate was 100%.Conclusion High-resolution CT has a higher diagnostic efficiency for early lung cancer in screening pulmonary nodules.
