摘要
目的 评估高分辨率计算机断层扫描(HRCT)在慢性阻塞性肺病(COPD)诊断中的应用价值,以提高疾病早期发现率和治疗效果。方法 选取2021年5月—2023年4月在本院确诊的120例COPD患者,根据诊断方式将其分为实验组(60例,HRCT诊断)和对照组(60例,常规胸部CT诊断)。比较两组在气道壁厚度、肺实质密度、肺气肿检出率、影像质量评分及诊断一致性(Kappa值)等方面的差异。结果 实验组T/D比为0.47±0.05,对照组为0.39±0.04,差异具有统计学意义(t=8.415,P<0.05)。实验组肺气肿检出率为91.67%(55/60),显著高于对照组的73.33%(44/60)(χ~2=6.846,P<0.05)。实验组肺实质低密度面积占比(LAA%)为(21.45±3.12)%,对照组为(17.98±2.84)%(t=6.324,P<0.05)。实验组影像质量评分为(4.72±0.21)分,高于对照组的(3.25±0.37)分(t=17.531,P<0.05)。在诊断一致性方面,实验组Kappa值为0.88,对照组为0.63,差异具有统计学意义(P<0.05)。结论 高分辨率CT在COPD诊断中的应用显著提高了病变检出率、影像学参数的准确性以及诊断一致性,其优越的影像质量和定量分析能力可为临床诊断提供更精准的依据,值得推广应用。
Objective To evaluate the application value of high resolution computed tomography(HRCT)in the diagnosis of chronic obstructive pulmonary disease(COPD),so as to improve the early detection rate and treatment effect of the disease.Methods 120 patients diagnosed with COPD in a hospital from May 2021 to April 2023 were selected and divided into experimental group(60 cases diagnosed with HRCT)and control group(60 cases diagnosed with conventional chest CT)according to the diagnosis method.Airway wall thickness,lung parenchyma density,emphysema detection rate,image quality score and diagnostic consistency(Kappa value)were compared between the two groups.Results Airway wall thickness(T/D ratio)was 0.47±0.05 in experimental group and 0.39±0.04 in control group,the difference was statistically significant(t=8.415,P<0.05).The detection rate of emphysema in the experimental group was 91.67%(55/60),which was significantly higher than that in the control group(73.33%(44/60))(χ2=6.846,P<0.05).LAA%of lung parenchyma was 21.45±3.12 in the experimental group and 17.98±2.84 in the control group,the difference was significant(t=6.324,P<0.05).The image quality score of the experimental group was 4.72±0.21,which was higher than that of the control group(3.25±0.37,t=17.531,P<0.05).The diagnostic consistency Kappa value was 0.88 in the experimental group and 0.63 in the control group,the difference was statistically significant(P<0.05).Conclusion The application of high-resolution CT in the diagnosis of COPD significantly improves the detection rate of lesions,the accuracy of imaging parameters and the consistency of diagnosis.Its superior image quality and quantitative analysis ability can provide a more accurate basis for clinical diagnosis,and it is worth promoting and applying.
