[Radionuclide evaluation of the relation between the upper and lower respiratory organs].

Functional examination of the lungs provides information on global pulmonary parameters. Radionuclide examination of pulmonary ventilation and gas distribution in the latter makes it possible to evaluate the functional regional finding in the lungs. In six subjects, using the bolus method with 133Xe, the respiratory system as a whole was examined and relations between upper and lower airways were evaluated.
