CT Neck Without and With IV Contrast There is no relevant literature to support the use of neck CT without and with IV contrast for initial evaluation of suspected bronchiectasis. CT Neck Without IV Contrast There is no relevant literature to support the use of neck CT without IV contrast for initial evaluation of suspected bronchiectasis. CTA Chest With IV Contrast There is no relevant literature to support the use of chest CTA for initial evaluation of suspected bronchiectasis. However, bronchiectasis can be detected incidentally on chest CTA with IV contrast performed for other indications. Tracheobronchial Disease FDG-PET/CT Skull Base To Mid-Thigh There is no relevant literature to support the use of FDG-PET/CT for initial evaluation of suspected bronchiectasis. MRI Chest Without and With IV Contrast There is no relevant literature to support the use of MRI chest without and with IV contrast for initial evaluation of suspected bronchiectasis. MRI Chest Without IV Contrast Limited data exist on the use of MRI without IV contrast in characterization of bronchiectasis. A small study of 23 adults with primary immunodeficiency found MRI inferior to CT in characterizing extent of bronchiectasis but found similar performance of MRI and CT in assessing severity of bronchiectasis, mucous plugging, bronchial wall thickening, and other associated parenchymal findings [47]. An exploratory study of 25 patients showed moderate agreement between MRI and CT scores for imaging findings in mycobacterium avium complex pneumonia, including for bronchiectasis [48]. However, the use of MRI for assessment of bronchiectasis is currently limited mainly to research settings or use in young patients such as those with cystic fibrosis. Radiography Chest Chest radiography is relatively insensitive for detection of bronchiectasis but is often performed as initial imaging in patients with respiratory symptoms that are common in patients with bronchiectasis [9,10].
