多层螺旋CT后处理技术在支气管结核诊治中的应用

摘要

Objective To analyze the CT features of bronchial tuberculosis by applying multi-slice spiral CT post-processing technology.Methods Eighty-five cases of clinically confirmed bronchial tuberculosis in the hospital underwent routine chest CT scan and enhanced scan,then the raw-data were conducted the post-processing in the AW workstation.Finally the CT features of bronchial tuberculosis were analyzed and summarized on the PACS workstation.Results A total of 153 bronchial lesions were found:15 lesions were in the right main bronchus,24 lesions in the right upper lobe bronchus,14 lesions in the intermediate bronchial,21 lesions in the right middle lobe bronchus,8 lesions in the right lower lobe bronchus;18 lesions in the left main bronchus,43 lesions in the left upper lobe bronchus(including 13 lesions in the left lingular bronchus) and 10 lesions in the left lower lobe bronchus.Solitary lesion was in 27 cases and multiple lesions were in 58 cases.Irregular thickening of bronchial wall was in 113 cases and uniform thickening of bronchial wall was in 40 cases.Conclusion Multi-slice spiral CT post-processing technique shows obvious advantages in the diagnosis of bronchial tuberculosis and can provide the important imaging evidence for clinical diagnosis and treatment of bronchial tuberculosis.%目的 通过多层螺旋计算机断层(CT)后处理技术的应用,分析支气管结核的CT表现特点.方法 选择该院经临床证实的支气管结核患者85例,全部先进行常规胸部CT平扫及增强扫描,然后在AW工作站对原始数据进行后处理,最后在PACS工作站上分析总结支气管结核的CT表现特点.结果 共发现支气管病变153处:右主支气管15处,右肺上叶24处,右肺中间段支气管14处,右肺中叶21处,右肺下叶8处;左主支气管18处,左肺上叶43处(其中舌叶13处),左肺下叶10处.单发27例,多发58例.管壁不规则增厚113处(占73.9%),均匀性增厚40处(占26.1%).结论 多层螺旋CT后处理技术显示支气管结核病变优势显著,可为临床诊治支气管结核提供重要影像依据.
