摘要
目的:探讨在肺部磨玻璃样小结节样良恶性鉴别诊断中应用肺部CT检查的临床价值.方法:以 2022 年 2月-2023 年 2 月本院收治的 56 例肺部磨玻璃样小结节患者为研究对象,并均开展肺部CT检查,以手术病理检查结果为金标准,比较肺部磨玻璃样小结节样良、恶性患者肺部CT影像学征象之间的差异性,同时分析肺部CT检查的诊断结果及其诊断结果与手术病理检查结果之间的一致性,并探讨肺部 CT 检查的诊断效能.结果:手术病理确诊 45 例肺部磨玻璃样小结节患者中,恶性结节 22 例,良性结节 34 例;恶性结节患者肺部CT影像学征象中病灶形态不规则、病灶界面模糊、有分叶征、有毛刺征、有囊状透亮影、密度混合的占比均明显高于良性结节患者,P＜0.05;肺部CT检查虽存在假阳性诊断及漏诊,但诊断准确性为 82.14%,敏感性为 95.45%,与手术病理检查结果比较,其检查一致性程度较高,Kappa=0.648,P＜0.001.结论:肺部CT检查在肺部磨玻璃样小结节良恶性鉴别诊断中具有较高判定价值,可为临床诊疗提供较准确的指导依据.
Abstract
Objective:To investigate the clinical value of pulmonary CT in the differential diagnosis of benign and malignant pulmonary ground glass nodules.Methods:A total of 56 patients with pulmonary ground-glass nodules admitted to our hospital from February 2022 to February 2023 were selected as the study objects,and CT examination of the lungs was carried out in all of them.The results of surgical and pathological examination were used as the gold standard to compare the differences in CT imaging signs between benign and malignant patients with pulmonary ground-glass nodules.At the same time,the diagnostic results of lung CT examination and the consistency between the diagnostic results and pathological examination results were analyzed,and the diagnostic efficacy of lung CT examination was discussed.Results:Among the 45 patients with pulmonary ground glass nodules,22 were malignant nodules and 34 were benign nodules.The proportion of irregular lesion shape,blurred lesion interface,lobed sign,burr sign,cystic clear shadow and mixed density in malignant nodules were significantly higher than those in benign nodules(P<0.05).Although there were false positive diagnosis and missed diagnosis in lung CT examination,the diagnostic accuracy was 82.14%,and the sensitivity was 95.45%.Compared with the results of surgical and pathological examination,the examination consistency was higher(Kappa=0.648,P<0.001).Conclusion:CT examination of lung has a high value in the differential diagnosis of benign and malignant pulmonary ground glass nodule,which can provide a more accurate guide for clinical diagnosis and treatment.
