The purpose of this study is to evaluate the role of high-resolution computed tomography (HRCT) versus chest radiography (CXR) in children with recurrent respiratory infections. Fifty-one cases, aged 2 months-13 years, who had a history of recurrent respiratory infections, were examined with CXR and HRCT. HRCT showed that 16/51 of the cases had bronchiectasis. CXR revealed findings of bronchiectasis only in 5 of the 16 cases. HRCT showed peribronchial thickening in 18 cases, whereas CXR showed the same finding in 5 patients. Overall, HRCT showed the underlying pathology and sequel of pulmonary lesions in 22 out of 51 cases, and linear densities in 12. Compared with the CXR, HRCT gives much more information.
