[The effect of direct x-ray contrast lymphography on pulmonary perfusion function].

Overall twenty-five persons (8 males and 17 females) were enrolled in a study on the influence of straight radiopaque lymphography with an oily substance, on the condition of pulmonary microcirculation, as evidenced by perfusion pulmoscintigraphy. There was a significant decrease in the accumulation of 99m-Tc-macroaggregate (TCK-8) in lower portions of both lungs 24 hours after the lymphography and normal dispersal 10 days after the study made. The authors suggest that the radiopaque substance might stimulate the inflammatory processes in chronic nonspecific diseases of the lungs.
