摘　　要：目的 :分析支气管扩张症(以下简称支扩)的HRCT征象 ,评价HRCT在支扩症诊断中的价值。材料和方法 :报告69例支扩病例均行HRCT扫描 ,其中34例同时给予了数字减影支气管碘水造影(DSB)对照。结果 :(1)支扩的HRCT表现有8种征象 ,其中常见的征象为印戒征、轨道征、胸膜下征 ,肿块征及云雾征尚无文献报道。(2)HRCT与DSB比较 ,两者在肺叶水平符合率为100 % ,肺段水平为85 %～100 %。结论 :HRCT对支扩诊断具有很高的诊断价值 ,作为胸片后的首选检查方法 ,可替代大部分支气管造影。Purpose: To study the signs of bronchiectasis on high resolution CT(HRCT)images, evaluate the significance of HRCT in the diagnosis of bronchiectasis. Materials and Methods: HRCT was performed in 69 patients with bronchiectasis. 34 of them also had digital subtraction bronchography(DSB). Results: (1)The HRCT appearances of bronchietasis included eight signs, in which the most common signs were signet ring,lack of bronchial tapering, and visualization of bronchi close to the pleura. Mass sign and cloud sign are reported only in this paper. (2)Comparing HRCT with DSB, the reliability was 100% at the lober level, and 85%～100% at segmental level. Conclusion: After chest radiography HRCT is the first choice valuable method for the diagnosis of bronchiectasis. It may reduce the need of bronchography in the diagnosis of bronchiectasis.
