摘要
目的:探讨支气管结核的螺旋CT影像特点及螺旋CT检查的价值。方法:选择某传染病医院2010年至2012年经纤维支气管镜活检及手术病理证实支气管结核、资料完整的64例患者,使用GE16层螺旋CT扫描后进行后处理,总结其CT特点。结果:①支气管改变表现为管腔不规则狭窄、光滑狭窄和闭塞;②肺内改变表现为阻塞性肺不张/实变、肺炎、肺气肿和肺内结核灶;③少见CT表现如肺门、纵膈淋巴结增大、管壁钙化、管腔内结节。结论:本病有特征性的CT表现,螺旋CT后处理图像能够更直观、有效的显示其病变特征,对其诊断有重要价值。
Objective:To study the features and value of 16-slice multi-detector CT(MDCT) in the diagnosis of endobronchial tuberculosis.Methods:64 cases in recent 3 years proved by bronchofiberscope and pathology were taken with 16-slice CT scan and post-processing technique.The CT features were analyzed.Results:①lesions of bronchial(irregular stenosis of bronchial,regular stenosis of bronchial and occlusion of bronchial);②lesions of lung(obstructive atelectasis/consolidation,pneumonia,emphysema and pulmonary tuberculosis foci);③rare CT features(hilar and mediastinal lymph node enlargement,tube wall calcification and nodule in the luminal).Conclusion:The characteristic CT features are observed and post-processing technique can display its manifestation more intuitively and effectively.The spiral CT is of importance in diagnosis of endobronchial tuberculosis.
