The authors evaluated historical patterns in the types of procedures performed in
diagnostic and therapeutic nuclear medicine and the associated radiation safety
practices used from 1945-2009 in a sample of U.S. radiologic technologists. In
2013-2014, 4,406 participants from the U.S. Radiologic Technologists (USRT) Study
who previously reported working with medical radionuclides completed a detailed
survey inquiring about the performance of 23 diagnostic and therapeutic
radionuclide procedures and the use of radiation safety practices when performing
radionuclide procedure-related tasks during five time periods: 1945-1964,
1965-1979, 1980-1989, 1990-1999, and 2000-2009. An overall increase in the
proportion of technologists who performed specific diagnostic or therapeutic
procedures was observed across the five time periods. Between 1945-1964 and
2000-2009, the median frequency of diagnostic procedures performed substantially
increased (from 5 wk to 30 wk), attributable mainly to an increasing frequency of
cardiac and non-brain PET scans, while the median frequency of therapeutic
procedures performed modestly decreased (from 4 mo to 3 mo). Also a notable
increase was observed in the use of most radiation safety practices from
1945-1964 to 2000-2009 (e.g., use of lead-shielded vials during diagnostic
radiopharmaceutical preparation increased from 56 to 96%), although lead apron
use dramatically decreased (e.g., during diagnostic imaging procedures, from 81
to 7%). These data describe historical practices in nuclear medicine and can be
used to support studies of health risks for nuclear medicine technologists.
