Radio-aerosol lung scintigraphy with technetium has been shown to precisely evaluate the extent of aerosol and particulate distribution and absorption through the entire air passage. In asthmatics receiving dry-powder inhalers as opposed to metered-dose inhalers, technetium scintigraphy may be used to demonstrate improved peripheral lung distribution of steroids. Ventilation defects may also be detected using technetium-99m DTPA.
