活动性肺结核治疗前后CT征象转归的对照研究

目的:探讨活动性肺结核抗结核治疗前后CT征象的变化规律。方法:搜集新发活动性肺结核32例,在抗结核治疗前后均行两次以上螺旋CT检查,对比观察活动性肺结核CT征象的演变与转归表现。结果:在活动性肺结核CT征象中,磨玻璃阴影、小叶中心结节影、树芽征、小叶实变阴影、肺实变、厚壁空洞及支气管壁增厚在治疗前后的检出率有显著差异(P<0.01);而支气管扩张、薄壁空洞和钙化在治疗前后无明显差异(P>0.05)。治疗前活动性肺结核可检出多种活动性CT征象,治疗后上述征象多以单发为主。结论:CT征象在活动性肺结核治疗前后具有一定的演变规律,有助于评价活动性肺结核治疗的疗效。

Comparative study of CT signs conversion of active pulmonary tuberculosis pre-and post-antituberculotic treatment

Objective:To investigate the CT signs conversion rules of active pulmonary tuberculosis pre-and post-treatment.Methods:32 new patients with active pulmonary tuberculosis were accumulated and taken more than twice SCT scanning pre-and post-antituberculotic treatment.The CT signs conversion and evolvement of active pulmonary tuberculosis were observed comparatively.Results:Among the CT signs of active pulmonary tuberculosis,there were apparent differences in the ground glass opacity,centrilobular nodule,tree-in-bud,lobular consolidation,pulmonary consolidation,thick-walled cavity and bronchial wall thickness pre-and post antituberculotic treatment(P<0.01);There were no significant differences in the bronchiectasis,thin-walled cavity and calcification pre-and post antituberculotic treatment(P>0.05).Before antituberculotic treatment,usually more active CT signs could be found in active tuberculosis lesion,but appeared one CT sign mostly after antituberculotic treatment.Conclusion:There is conversion rule of CT signs in active pulmonary tuberculosis pre-and post-antituberculotic treatment, and CT is helpful in the evaluation of antituberculotic treatment results of active tuberculosis.
