[Feasibility of combined roentgeno-radionuclide studies of the lungs in preventive mass screening of workers in an industrial enterprise].
1991
: The results of a combined roentgeno-radionuclide investigation of the lungs were studied in 45 persons at risk of developing chronic nonspecific pulmonary diseases, diagnosed in a mass screening of 3000 workers at an industrial enterprise. The results of fluorographic, roentgenoscopic and roentgenographic investigations of the lungs, roentgeno-pneumopolygraphy and radionuclide investigation of lung perfusion (pulmoscintigraphy with 99mTc-labeled albumin macroaggregates) were compared. During this combined investigation the signs of nonspecific pulmonary diseases were diagnosed in 40% of the patients, changes of the pulmonary blood flow--in 71%, changes in ventilation--in all the examinees. A conclusion was made of the necessity of additional combined investigation of patients belonging to risk groups, identified during mass screenings.
