摘　　要：目的　研究支气管扩张 (支扩 )病人的肺高分辨率CT的呼气相表现。方法　 2 1例支扩患者进行HRCT的吸、呼气相扫描的肺功能检查 ,观察支扩和空气潴留的累及范围 ,统计患者双肺吸 -呼气相密度差值 (VD)、面积缩小率 (AR)和空气潴留评分值 ,将它们与肺功能试验结果进行相关性分析。结果　空气潴留征可见于支扩未累及的层面 ;双肺VD、双肺AR、空气潴留评分值与肺功能试验的结果存在显著性相关。结论　呼气相HRCT辅助吸气相能对支扩进行评价。Objective To study the findings on expiratory HRCT scan in patients with bronchiectasis.Methods 21 patients with bronchiectasis underwent inspiratory and expiratory HRCT scan and pulmonary function test(PFT),the area involved with bronchiectasis or air-trapping was examined.The inspiratory-expiratory value difference (VD),area reduction ratio(AR)of bilateral lungs and air-trapping score of bilateral lungs were calculated.Then they were statistically correlated with PFT results.Results Air trapping involved areas without bronchiectasis.VD and AR of bilateral lungs and air trapping score were statistically correlated with PFT results.Conclusion Expiratory HRCT scan may be an adjunctive method in evaluating bronchiectasis,the ventilation function of lungs can be evaluated with quantitative index.
