【摘要】 目的 分析支气管扩张 (以下简称支扩 )的HRCT征象 ,探讨HRCT在支扩诊断中的价值。 方法 回顾性分析56例支扩患者常规胸部CT、HRCT表现。结果 56例支扩患者有53例HRCT清晰显示了支气管扩张的部位、类型和范围。支扩的HRCT扫描常见的征象为印戒征、轨道征、胸膜下征。而常规CT显示37例支扩 ;常规CT和HRCT对支扩的检出敏感性分别为66%和94.6%。结论 HRCT对支气管扩张患者尤其无明显症状者的诊断具有重要的价值更多还原

【Abstract】 Objective To study the signs of bronchiectasis on high resolution CT(HRCT)images, and evaluate the value of HRCT in diagnosis of bronchiectasis. Methods The findings of conventional CT and HRCT on 56 patients with bronchiectasis were reviewed retrospectively. Results The anatomic distribution,type,and extent of bronchiectasis on HRCT in 53 cases were shown clearly,while only in 37cases on conventional CT.The HRCT appearances of bronchiectasis included six signs,in which the most common signs were signet ring,lack of bronchial tapering,and visualization of bronchi close to the pleuta. The detecting sensitivity of bronchiectasis by chest conventional CT and HRCT was 66% and 94.6% respectively.Conclusion HRCT is helpful in the assessment of the antitypical brochiectasis.It may replace the need of bronchography in the diagnosis of bronchiectasis.更多还原
