Regional lung function in asbestos workers.
Regional lung function was measured using radioactive xenon-133 in a group of normal subjects and in two groups of asbestos workers. When compared with the normal group, patients with pulmonary asbestosis showed impaired ventilation of the lower zones. Subjects with calcified pleural plaques without radiological evidence of lung parenchymal fibrosis did not show this abnormality.
