Abstract

Magnetic resonance imaging (MRI) of the airway has recently emerged as a diagnostic tool for evaluating tracheobronchial obstruction in pediatric patients. Computer-assisted reconstructions of transaxial images have enabled three-dimensional reconstructions of the airway to be manipulated in any plane and visualized in relation to adjacent anatomical structures. Eight patients in whom magnetic resonance imaging was used to diagnose a variety of airway obstructive lesions are presented. A protocol for the evaluation of pediatric tracheobronchial obstruction is presented, with the role of three dimensionally reconstructed MR imaging emphasized.
