[Radioaerosol lung imaging in small airways disease (author's transl)].
Aerosol inhalation lung imaging was performed in 35 asymptomatic smokers who have been selected on the basis of abnormal findings in small airways pulmonary function tests. Qualitative (image inspection) and quantitative (aerosol distribution index = ADI) analysis of the radioaerosol lung patterns was accomplished. Compared to healthy subjects as well as to patients with chronic obstructive lung disease significant differences of mean aerosol distribution homogeneity were observed. A characteristic  type of abnormal aerosol pattern, indicating peripheral airways obstruction, was found in 71% of the patients with small airways disease.
