High-resolution computed tomography in pediatric patients with postinfectious bronchiolitis obliterans.

The authors performed a prospective cohort study to define the high-resolution computed tomography features of 31 pediatric patients with postinfectious bronchiolitis obliterans. All patients underwent chest radiographs and lung perfusion scans, and 27 of the 31 patients underwent high-resolution computed tomography of the lung. The most common abnormal features shown on computed tomography included bronchial wall thickening, bronchiectasis, and areas of increased and decreased attenuation. High-resolution computed tomography showed a higher sensitivity than both chest radiography and lung perfusion scanning in detecting pulmonary abnormalities in these patients.
