A simple radioaerosol generator and delivery system for pulmonary ventilation studies

Details of a simple radioaerosol generator and delivery system are presented. Aerosol streams of 99mTc-DTPA solution of different distributions were produced. The most useful distribution had an activity median aerodynamic diameter (AMAD) of 0.9 μm with a geometric standard deviation of 1.5. This distribution also had more than 96% of aerosol particles with… CONTINUE READING
