摘　　要：目的探讨胸部高分辨率CT及后处理技术诊断支气管扩张的作用。方法将80例支气管扩张并咯血住院病人以单纯性支气管扩张/支气管扩张合并慢性肺部疾病分A、B两组;分别对其MSCT图像进行回顾性分析、总结,采用多平面重组及最小密度投影联合应用,并以不同层厚及窗口技术进行观察。结果广泛性支气管扩张A组占60.00%,以囊状型(蜂窝样)及混合型为主。2～4肺叶支气管扩张B组占约66.66%,以柱状型(柱状、杵状)及混合型为主;肺结核继发支气管扩张约占17.50%。结论CT后处理技术多平面重组薄层及最小密度投影3～5 mm厚度层块(厚块)对诊断支气管扩张有明显优势,利于发现病变支气管,减少诊断时耗。Objective To investigate the effect of high resolution CT in the diagnosis of bronchial dilation (extension) and the effect of post treatment technique.Methods Eighty inpatients with bronchiectasis and hemoptysis were divided into two groups: simple bronchiectasis/bronchiectasis with chronic pulmonary disease.The MSCT images were analyzed retrospectively and summarized.The multi-plane recombination (MPR) and the minimum density projection (MinIP) were used together.The different layer thickness and window technique were used to observe.Results The extensive adduction of group A was accounted for 60.00% with cystic type (honeycomb type) and mixed type.Patients with 2-4 lobar branchectasis in Group B was accounted for 66.66%,with columnar type (columnar and clubbed) and mixed type.The secondary incidence of tuberculosis was accounted for 17.50%.Conclusion CT post-processing technique MPR thin layer and MinIP 3-5 mm thickness block (thick block) have obvious advantages in diagnosing bronchiectasis.It is helpful to find the diseased bronchus and reduce the time consuming in diagnosis.
