Radiologic evaluation of the trachea.
Tracheal lesions are categorized into stenoses of various etiologies, inflammatory lesions, benign and malignant tumors, vascular anomalies affecting the trachea, and miscellaneous conditions including amyloid, polychondritis, and tracheobronchopathia osteochondroplastica. For evaluation of the extent and characterization of these lesions, different radiologic modalities can be utilized, which include fluoroscopy with barium swallow, conventional films, linear tomography, computerized tomography scan, and magnetic resonance imaging, including magnetic resonance angiography. The radiologic indications and findings are described in this article.
