CT Chest Without IV Contrast Chest CT is widely used for first-line imaging evaluation of central airway pathology such as masses, thickening, and stenosis. CT without IV contrast readily depicts central airway lesions, thickening, and stenosis. CT has shown high correlation with findings at bronchoscopy and offers additional advantages by depicting degree of stenosis, extraluminal involvement of lesions, and extension to adjacent structures [20,21]. CT allows assessment of the location, shape, dimensions, mural extent, and attenuation characteristics of tumors of the large airways and detection of intrathoracic disease in cases of malignancy [19,20]. CT Neck and Chest With IV Contrast There is no relevant literature to support the use of neck and chest CT with IV contrast in the initial evaluation of suspected tracheal stenosis. However, combined neck and chest CT with IV contrast can be performed for Tracheobronchial Disease assessment of suspected tracheal lesions and stenosis, especially for diseases that can involve the subglottic trachea, such as diffuse tracheal diseases and suspected or known malignancies of the neck. Chest CT protocols to evaluate tracheal stenosis often prescribe z-axis coverage through the lower neck. CT Neck and Chest Without and With IV Contrast There is no relevant literature to support the use of neck and chest CT without and with IV contrast in the initial evaluation of suspected tracheal stenosis.
