摘要
目的比较CT与传统X线诊断慢阻肺合并肺间质纤维化的效果。方法选取2019年8月~2020年8月我院接诊的92例疑似慢阻肺合并肺间质纤维化患者为研究对象,均进行CT、传统X线检查,与病理检查为标准,比较两种检测方法诊断效果、准确率、敏感度、特异度、不同程度肺气肿诊断率以及征象显示率。结果经一致性检测显示CT诊断Kappa值为0.954,传统X线检查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准确率、敏感度、特异度均高于传统X线,差异有统计学意义(P<0.05);CT诊断轻度肺气肿准确率高于传统X线诊断,差异有统计学意义(P<0.05),中度、重度诊断准确率与传统X线诊断比较,差异无统计学意义(P>0.05)。CT检查征象(肺纹理紊乱和增强、边缘致密影、肺大疱、小叶间隔增厚、支气管扩张)显示率均高于传统X线检查,毛玻璃样高密度影显示率低于传统X线检查比较,但差异无统计学意义(P>0.05)。结论CT诊断慢阻肺合并肺间质纤维化准确率、敏感度以及特异度均高于传统X线检查,可提高轻度肺气肿诊断准确率,且各检查征象显示率更优,可为临床早期慢阻肺合并肺纤维化提供可靠的诊断和治疗依据。
Objective To compare the effects of CT and traditional X-ray diagnosis of COPD with pulmonary interstitial fibrosis.Methods A total of 92 patients with suspected COPD complicated with pulmonary interstitial fibrosis who were admitted to our hospital from August 2019 to August 2020 were selected as the research subjects.CT,traditional X-ray examinations and pathological examinations were performed as standard.The diagnostic effect,accuracy,sensitivity,specificity,diagnosis rate of different degrees of emphysema,and the rate of sign display were compared between the two detection methods.Results The consistency test showed that 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 accuracy,sensitivity,and specificity of CT in the diagnosis of COPD complicated with pulmonary fibrosis were higher than those of traditional X-ray,the difference was statistically significant(P<0.05);The accuracy of CT diagnosis of mild emphysema was higher than that of traditional X-ray diagnosis,the difference was statistically significant(P<0.05).Compared with traditional X-ray diagnosis,the accuracy of moderate and severe diagnosis was not statistically different(P>0.05).CT examination signs(pulmonary texture disorder and enhancement,edge compact shadow,pulmonary bullae,interlobular thickening,bronchiectasis)were higher than traditional X-ray examinations,and ground-glass-like high-density shadows showed lower rates than traditional X-ray examinations,but the difference was not statistically significant(P>0.05).Conclusion The accuracy,sensitivity,and specificity of CT in the diagnosis of COPD with pulmonary fibrosis are higher than traditional X-ray examinations,which can improve the diagnostic accuracy of mild emphysema,and the display rate of each examination sign is better,which can be COPD combined with pulmonary fibrosis in the early clinical stage provides a reliable basis for diagnosis and treatment.
