摘要
目的探究肺结节患者计算机断层扫描(CT)诊断特征,分析肺部影像报告和数据系统(Lung-RADS)对肺结节的诊断价值。方法回顾性分析2018年3月至2019年3月于我院经病理活检或手术确诊的肺结节患者136例,共有肺结节160个。观察患者肺结节的CT征象,分析其诊断特征。根据Lung-RADS分级标准进行分级,对比分析Lung-RADS分级的诊断价值。结果CT征象中结节大小、边缘、钙化、胸膜牵拉征、毛刺征、分叶征、肿瘤血管征、支气管截断征对诊断良恶性肺结节有影响(P<0.05),空泡征、支气管充气征对诊断良恶性肺结节无影响(P>0.05)。Lung-RADS分级结果中,1级、2级的阴性预测率分别为100.0%、90.91%;3级、4A级、4B级、4X级的阳性预测率分别为69.57%、68.97%、71.21%、91.67%。CT征象、Lung-RADS分级以及联合诊断良恶性肺结节的曲线下面积分别为0.735、0.618、0.914。结论CT征象对肺结节的筛查和鉴别诊断有着重要的临床参考价值。Lung-RADS分级联合CT征象诊断能够对结节筛查进行有效的分类,对于良恶性肺结节的诊断具有较高的临床价值。
Objective To explore the diagnostic features of computed tomography(CT)in patients with pulmonary nodules and analyze the diagnostic value of lung imaging reports and data systems(Lung-RADS)for pulmonary nodules.Methods A total of 160 pulmonary nodules of 136 patients with pulmonary nodules diagnosed by pathological biopsy or surgery in our hospital from March 2018 to March 2019 were retrospective analyses.The CT signs of the pulmonary nodules were observed,and the diagnostic features were analyzed.The classification was performed according to the Lung-RADS classification standard,and the diagnostic value of the Lung-RADS classification was compared and analyzed.Results CT features such as nodule size,margin,calcification,pleura pull sign,hair prick sign,lobulation sign,tumor vascular sign,bronchial truncation sign were associated with the diagnosis of benign and malignant pulmonary nodules(P<0.05);vacuole sign,bronchiectasis sign was not associated with the diagnosis of benign and malignant pulmonary nodules(P>0.05).In the Lung-RADS grading results,the negative predictive rates of grade 1 and grade 2 were 100.0%and 90.91%,respectively;the positive predictive rates of grade 3,grade 4A,grade 4B,and grade 4X were 69.57%,68.97%,71.21%,and 91.67%respectively.The area under the curve of CT signs,lung rads classification,and combination of the two methods diagnosis of benign and malignant pulmonary nodules were 0.735,0.618,and 0.914,respectively.Conclusion CT signs have important clinical reference value for the screening and differential diagnosis of pulmonary nodules.Lung-RADS classification combined with CT diagnosis can effectively classify the pulmonary nodules,which has a high clinical value for diagnosing benign and malignant pulmonary nodules.
