Bronchoscopy and MDCT are routinely used to assess tracheobronchomalacia (TBM). Recently, dynamic MRI (cine MRI) has been proposed as a radiation-free alternative to MDCT. In this study, we tested cine MRI assessment of airway dynamics during various breathing conditions and compared cine MRI and MDCT measurements in healthy volunteers and patients with suspected TBM.
Cine MRI was found to be a technically feasible alternative to MDCT for assessing central airway dynamics.
支气管镜检查和 MDCT 通常用于评估气管支气管软化症（TBM）。最近，动态 MRI（电影 MRI）已被提议作为 MDCT 的无辐射替代方法。在这项研究中，我们测试了电影 MRI 在各种呼吸条件下评估气道动力学的能力，并比较了健康志愿者和疑似 TBM 患者的电影 MRI 和 MDCT 测量结果。
电影 MRI 被发现是一种可行的替代 MDCT 技术，可用于评估中央气道动力学。
