CT Neck and Chest Without IV Contrast There is no relevant literature to support performing a full neck CT in this setting, however, z-axis coverage through the lower neck is often prescribed as part of a standard chest CT without IV contrast for evaluation of suspected tracheomalacia or bronchomalacia. CT Neck With IV Contrast There is no relevant literature to support the use of neck CT with IV contrast for initial evaluation of suspected tracheomalacia or bronchomalacia. CT Neck Without and With IV Contrast There is no relevant literature to support the use of neck CT without and with IV contrast for initial evaluation of suspected tracheomalacia or bronchomalacia. CT Neck Without IV Contrast There is no relevant literature to support the use of neck CT without IV contrast for initial evaluation of suspected tracheomalacia or bronchomalacia. CTA Chest With IV Contrast There is no relevant literature to support the use of chest CTA for initial evaluation of suspected tracheomalacia or bronchomalacia. Tracheobronchial Disease FDG-PET/CT Skull Base To Mid-Thigh There is no relevant literature to support the use of FDG-PET/CT for initial evaluation of suspected tracheomalacia or bronchomalacia. MRI Chest Without and With IV Contrast There is no relevant literature to support the use of MRI chest without and with IV contrast for initial evaluation of suspected tracheomalacia or bronchomalacia. Radiography Chest Dynamic chest radiography has been proposed for evaluating ECAC but use has been limited to small preliminary research investigations [34]. Chest radiography may be used in the initial evaluation of other pulmonary diseases that may manifest with respiratory symptoms also seen in ECAC. Radiography Neck There is no relevant literature to support the use of neck radiography for initial evaluation of suspected tracheomalacia or bronchomalacia. Variant 4: Adult. Tracheomalacia or bronchomalacia. Pre- or posttreatment assessment.
