"With the development of inexpensive small plastic nebulizers allowing submicron aerosols in the 1970s, DTPA was considered an appealing alternative to Xe-133 (half-life 5 days) or Kr-81m (half-life 13 seconds) for ventilation imaging. The Nuclear Regulatory Commission was petitioned to allow for the use of aerosols of Tc-99m-DTPA for inhalation studies, which it approved in 1983 2."
