A systematic review of 122 studies found 42 quantitative CT scoring methods in the research literature, including calculation of bronchial-arterial ratios, bronchial diameters, or bronchial surface area [43]. Severity of bronchiectasis at CT correlates with measures of airflow obstruction [40]. A relatively large prospective cohort study of 608 patients with bronchiectasis examined the association between a variety of clinical, laboratory, and CT findings and clinical outcomes; a CT finding of bronchiectasis in at least 3 lobes was associated with poorer outcomes and was incorporated along with several clinical variables into a bronchiectasis severity score with relatively high predictive value for exacerbations, hospitalizations, and mortality in patients with bronchiectasis [44]. A prospective multicenter study of 261 patients with non-CF bronchiectasis found weak but statistically significant correlations between severity and extent of bronchiectasis at CT and forced expiratory volume in one second and forced vital capacity [45]. A study of 277 patients with NTMB found correlations between bronchiectasis (as assessed by semiquantitative scores) and clinical variables such as more frequent exacerbations and lower blood oxygenation [46]. CT Neck and Chest With IV Contrast There is no relevant literature to support the use of neck and chest CT with IV contrast for initial evaluation of suspected bronchiectasis. 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 for initial evaluation of suspected bronchiectasis. CT Neck and Chest Without IV Contrast There is no relevant literature to support the use of neck and chest CT without IV contrast for initial evaluation of suspected bronchiectasis. CT Neck With IV Contrast There is no relevant literature to support the use of neck CT with IV contrast for initial evaluation of suspected bronchiectasis.
