Early computed tomography modifications following bronchial thermoplasty in patients with severe asthma

Bronchial thermoplasty (BT) is a recent, promising and well-tolerated technique for the treatment of severe asthma. By delivering thermal energy to the airway wall, this procedure can induce early pulmonary opacities seen on computed tomography (CT). We aimed to examine early CT modifications induced by BT and to determine their association with respiratory symptoms. Unenhanced chest CT was performed the day after each BT session in 13 patients...
