慢阻肺合并肺间质纤维化经CT与传统X线诊断的效果分析

The Analysis on the Effect of CT and Traditional X-ray Diagnosis of Chronic Pbstructive Pulmonary Disease(COPD) with Pulmonary Fibrosis

目的:探究对慢阻肺合并肺间质纤维化患者实施CT、传统X线诊断的效果。方法:随机抽取2016年12月至2018年4月深圳市宝安区沙井人民医院106例疑似慢阻肺合并肺间质纤维化患者为观察对象,对其实施CT、传统X线诊断,以临床最终诊断结果为参照,对比CT、传统X线的诊断效果。结果:经一致性检测显示CT诊断的Kappa值为0.954,提示一致性良好;传统X线检查的Kappa值为0.798,提示一致性良好。CT诊断慢阻肺合并肺间质纤维化的敏感度(97.98%)及总准确率(97.17%)较传统X线(81.63%、81.13%)更高,P<0.05。CT图像显示大部分患者肺门阴影增加,肺部纹理增强、紊乱,小叶间隔增厚,可见支气管血管束变细。X线图像显示大部分患者肺部纹理增强、紊乱,呈弥漫性分布,部分患者可见边缘模糊的结节状、小片状、点状致密阴影。结论:对慢阻肺合并肺间质纤维化患者实施CT诊断的效果较传统X线更佳。

Objective: To explore the effect of CT, traditional X-ray diagnosis in patients with COPD complicated with pulmonary interstitial fibrosis. Methods: From December 2016 to April 2018, 106 patients suspected of COPD complicated with pulmonary interstitial fibrosis were randomly selected as observation objects. The traditional X-ray diagnosis of CT, was performed in our hospital, and the results were compared with the final clinical diagnosis. To compare the diagnostic effect of traditional CT, X-ray. Results: The Kappa value of CT diagnosis was 0.954, indicating good consistency;The Kappa value of traditional X-ray examination was 0.798, indicating good consistency. The sensitivity(97.98%) and the total accuracy(97.17%) of CT in diagnosing pulmonary interstitial fibrosis were higher than those in traditional X-ray(81.63%, 81.13%), P<0.05. CT images showed that most of the patients had increased hilar shadow and enhanced lung texture. The bronchovascular bundles were thickened and the bronchovascular bundles were thinned. X-ray images showed that most of the patients had enhanced and disordered pulmonary textures with diffuse distribution. Some of the patients could see nodular, flaky and punctate dense shadows with blurred edges. Conclusion: CT is more effective than traditional X-ray in diagnosis of COPD complicated with pulmonary interstitial fibrosis.
