Summary

Scattered radiation during videofluoroscopy for swallowing studies (VFSS) poses minimal risk. Exposure levels to surrounding individuals were found to be well within acceptable safety limits, ensuring patient and staff safety.

Area of Science:

  • Radiological Sciences
  • Medical Imaging
  • Radiation Safety

Background:

  • Videofluoroscopy for swallowing studies (VFSS) is a common diagnostic procedure.
  • Understanding scattered radiation exposure is crucial for radiation safety protocols.
  • Limited data exists on the environmental radiation exposure during VFSS.

Purpose of the Study:

  • To quantify scattered radiation exposure to the surroundings during VFSS.
  • To assess the radiation dose to individuals near patients undergoing VFSS.
  • To establish safety parameters for VFSS procedures.

Main Methods:

  • Scattered radiation was measured using an ion chamber survey meter in 17 adult patients.
  • Cumulative dose area product (DAP) was recorded for each videofluoroscopy procedure.

  • A formula was derived to estimate scattered radiation dose at various distances based on DAP.

    • Main Results:

    • Mean scattered radiation exposure at 150 cm was 149 ± 78 microR; mean DAP was 842 ± 544 cGy·cm².
    • Estimated mean scattered radiation dose to muscle tissue at 30-100 cm ranged from 33.68 to 3.03 microSv.
    • A predictive formula for scattered radiation dose was developed based on DAP.

    Conclusions:

    • Scattered radiation exposure during VFSS is within acceptable safety limits.
    • The derived formula aids in estimating radiation doses to bystanders.
    • VFSS can be performed safely with appropriate radiation monitoring.
