This study estimated patient radiation doses from barium procedures. Fluoroscopy contributed more to dose than radiography, with barium enema and enteroclysis yielding higher doses, highlighting the need for improved radiation protection training.

Area of Science:

  • Medical Imaging
  • Radiology
  • Radiation Dosimetry

Background:

  • Barium procedures are common diagnostic tools in radiology.
  • Accurate estimation of patient radiation dose is crucial for radiation protection.
  • Understanding dose contributions from fluoroscopy versus radiography is important.

Purpose of the Study:

  • To estimate patient doses, including dose-area product, organ dose, effective dose, and entrance surface dose, for various barium procedures.
  • To compare radiation doses across different barium examination categories.
  • To identify factors influencing patient dose and suggest methods for dose reduction.

Main Methods:

  • Analysis of 175 barium procedures across five examination categories in 175 patients.
  • Dose-area product measured using a transmission ionization chamber.

  • Organ dose and effective dose calculated using examination data and specialized software.

    • Main Results:

    • Fluoroscopy contributed more to total patient dose than radiography in all analyzed procedures.
    • Higher dose-area product values were observed for double contrast barium enema, enteroclysis, and intestinal tract procedures.
    • Average effective doses ranged from 1.04 mSv (oesophageal tract) to 13.99 mSv (enteroclysis); oesophageal tract entrance surface dose was significantly lower.

    Conclusions:

    • Patient doses in barium procedures vary significantly depending on the examination type.
    • Enteroclysis and double contrast barium enema procedures result in higher patient doses.
    • Enhanced training in radiation protection for radiologists and specialists can lead to patient dose reduction in barium procedures.
