CT Neck Without IV Contrast Neck CT without IV contrast may occasionally be performed as a targeted assessment of known lesions within the superior trachea, including primary neck malignancies with tracheal involvement. However, the limited z-axis coverage of neck CT risks exclusion of the full extent of tracheal disease. More commonly, neck CT may be performed as part of a combined neck and chest CT for pre- or posttreatment assessment of tracheal lesions and stenosis. CTA Chest With IV Contrast Chest CTA with IV contrast may be used in preoperative evaluation of tracheal stenosis in the setting of extrinsic compression due to a vascular cause, such as aberrant vessel or aneurysm. Chest CTA with aortic contrast phase timing may be used in selected cases to evaluate suspected bleeding as a complication of tracheal interventions. MRI Chest Without and With IV Contrast Although tracheal imaging can be performed with MRI, including dynamic imaging, this tool has been used mainly as a research tool. MRI Chest Without IV Contrast Although tracheal imaging can be performed with MRI, including dynamic imaging, this tool has been used mainly as a research tool. Tracheobronchial Disease Radiography Chest There is no relevant literature to support the use of chest radiography for pretreatment evaluation of tracheal stenosis. Although there is no relevant literature to support the routine use of chest radiographs after procedures designed to treat tracheal stenosis, in practice chest radiographs may be obtained to evaluate possible complications such as pneumothorax, excessive pneumomediastinum, or aspiration. Radiography Neck There is no relevant literature to support the use of neck radiography for pre- or posttreatment evaluation of tracheal stenosis. Variant 3: Adult. Clinically suspected tracheomalacia or bronchomalacia. Initial imaging.
