Lung inhalation scintigraphy: development of a new aerosol system

A new technique for lung inhalation scintigraphy is reported, developing a new aerosol system, based on the original system of Taplin [1]. With two small compact polypropylene reservoirs, this 99Tcm DTPA technique allowed continuous breathing during the inhalation period. This system proved to be a useful alternative to that using radioactive gases and the system of Taplin, due to its low cost and the ease with which several projections may be obtained.
