Comparative Study
[Diagnosis of tracheal instability: spiral CT in inspiratory and expiratory and respiratory cine CT].
In tracheo- and bronchomalacia, localization and determination of collapse is necessary for planning a surgical procedure. We compared inspiratory and spiral CT, cine CT, and bronchoscopy and evaluated the relevance of each method. ⋯ Paired inspiratory and expiratory spiral CT localizes tracheal stenoses and demonstrates clinically relevant extraluminal compression. Improved evaluation of expiratory collapse and further information of localized tracheal instability is provided by cine CT.
