多层螺旋CT支气管图像后处理技术在气管支气管结核患者诊断中的研究

Multi-Slice Spiral CT Bronchial Image Post-Processing Technique in Gas Study on Diagnosis of Patients with Tub Ulobronchial Tuberculosis

目的:分析在气管支气管结核疾病确诊中应用多层螺旋CT支气管图像后处理技术的诊断价值。方法:回顾性收集龙岩市第二医院2021年5月~2023年5月存在有咳痰、发烧、盗汗、呼吸困难、咯血等临床症状且接受多层螺旋CT后高度怀疑气管支气管结核疾病的患者76例为研究对象,所有研究对象均接受多层螺旋CT支气管检查,将未经处理的原始图像资料作为对照组,将经图像后处理技术的图像资料作为观察组,以术后病理活检为金标准,对比两组图像资料阳性率、诊断效能以及在支气管管壁增厚、支气管管腔扩张、支气管钙化、肺损毁等影像学征象的显示率。结果:观察组图像后处理技术阳性率98.52%,明显高于对照组的图像资料阳性率92.64%;且在敏感度、特异度、符合率以及Kappa等诊断效能的对比上,观察组更高,而在影像学管壁增厚、狭窄、扩张等显示率上,同样为观察组更高,差异对比有统计学意义,P<0.05。结论:在气管支气管结核疾病确诊中应用多层螺旋CT支气管图像后处理技术可提高阳性检测率,同时对气管支气管结核影像征象有较好显示,诊断价值接近病理学检查金标准,利于临床确诊气管支气管结核,尽早开展对患者的相关诊治。

Objective:To analyze the diagnostic value of applying multi-slice spiral CT bronchial images in the diagnosis of tracheobronchial tuberculosis disease.Methods:A retrospective study was conducted on 76 patients with clinical symptoms such as sputum,fever,night sweats,dyspnea,and hemoptysis who were highly suspected of having tracheobronchial tuberculosis after receiving multi-slice spiral CT at Longyan Second Hospital from May 2021 to May 2023.All study subjects underwent a multi-slice spiral CT bronchial examination,unprocessed raw image data were used as the control group,the image data with the image post-processing technology is used as the observation group,using a postoperative pathological biopsy as the gold standard,the positive rate of image data,diagnostic efficacy and imaging rate of bronchial wall thickening,bronchial lumen dilation,bronchial calcification,and lung damage were compared.Results:The positive rate of images in the observation group was 98.52%.The positive rate of significantly higher than control group was 92.64%.In addition,in the comparison of sensitivity,specificity,coincidence rate and Kappa,the observation group was higher,while in the display rate of imaging wall thickening,stenosis and expansion,the same observation group was higher,and the difference was statistically significant,P<0.05.Conclusion:In tracheobronchial tuberculosis disease diagnosis of multi-slice spiral CT bronchial image postprocessing technology can improve the positive detection rate,at the same time the tube bronchial tuberculosis images have good show,according to the diagnostic value close to pathological examination gold standard,conducive to clinical diagnosis of tububronchial tuberculosis,related diagnosis and treatment of patients as soon as possible.
