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. Radiography Chest Radiography is often performed as initial imaging in patients with respiratory symptoms. Although tracheal stenosis and masses are occasionally incidental findings at chest radiography, the modality is much less sensitive for detection of central airway pathology than cross-sectional imaging. In a study of 41 patients with tumors and nonneoplastic stenosis of the central airways, radiography performed poorly compared to CT in depicting and characterizing lesions [22]. Radiography may be useful as an evaluation of possible complications of central airway disease, such as postobstructive atelectasis or pneumonia. Tracheobronchial Disease Radiography Neck There is no relevant literature to support the use of neck radiography in the initial evaluation of suspected tracheal stenosis. Radiography of the neck may be obtained in patients with suspected upper airway obstruction due to certain infections or foreign bodies. However, it is not routinely used for evaluation of tracheal stenosis. Variant 2: Adult. Tracheal or bronchial stenosis. Pre- or posttreatment assessment. CT Chest With IV Contrast CT of the chest with IV contrast can be used for pretreatment assessment of lesions and stenosis of the large airways and can help determine suitability and type of surgical or nonsurgical treatment approach [24]. However, studies comparing performance of chest CT with IV contrast to chest CT without IV contrast for evaluation of tracheal stenosis and associated lesions are lacking.
