Konietzke P, et al. - Given that bronchial thermoplasty (BT) can be considered in the treatment of severe asthma to reduce airway smooth muscle mass and bronchoconstriction, researchers tested the premise that BT might have long-term effects on airway dimensions and air-trapping detectable by quantitative computed tomography (QCT). In patients with severe asthma after BT, QCT could evaluate post-interventional airways changes. They found that BT decreases airway narrowing and air-trapping. The study findings suggested that QCT might be used in therapy guidance and monitoring.
