Chest CT protocols to evaluate tracheal stenosis often prescribe z-axis coverage through the lower neck. CT Neck With IV Contrast Neck CT with 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 assessment of suspected tracheal lesions and stenosis. CT Neck Without and With IV Contrast There is no relevant literature to support the use of neck CT without and with IV contrast in the initial evaluation of suspected tracheal stenosis. 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 assessment of suspected tracheal lesions and stenosis. CTA Chest With IV Contrast Chest CT angiography (CTA) with IV contrast may be used in evaluation of suspected tracheal stenosis in the setting of extrinsic compression due to a vascular cause, such as aberrant vessel or aneurysm. However, there is no relevant evidence comparing chest CTA and standard chest CT with or without IV contrast in initial evaluation of suspected tracheal stenosis. FDG-PET/CT Skull Base To Mid-Thigh Fluorine-18-2-fluoro-2-deoxy-D-glucose (FDG)-PET/CT is often used in the initial staging and follow-up of known thoracic malignancies, including tracheal tumors. However, FDG-PET/CT is not usually obtained as the initial imaging assessment of suspected tracheal stenosis.
