Abstract

We report here on the redistributed regional ventilation abnormalities after the administration of a bronchodilator and as seen on xenon-inhaled dual-energy CT in a patient with asthma. The improved ventilation seen in the right lower lobe and the decreased ventilation seen in the right middle lobe after the administration of a bronchodilator on xenon-inhaled dual-energy CT could explain a positive bronchodilator response on a pulmonary function test. These changes may reflect the heterogeneity of the airway responsiveness to a bronchodilator in patients with asthma.

摘要

我们在此报告一例哮喘患者吸入氙气双能 CT 后支气管扩张剂治疗后区域性通气异常再分布的病例。吸入氙气双能 CT 支气管扩张剂治疗后，右下叶通气改善，右中叶通气减少，这可以解释肺功能检查中支气管扩张剂的阳性反应。这些变化可能反映了哮喘患者气道对支气管扩张剂反应的异质性。
