    This study measured radiation doses during ERCPs and pneumo-colons. Colon exams deliver significantly higher gonadal radiation than ERCPs, but less to other organs.

    Area of Science:

    • Medical Physics
    • Radiology
    • Radiation Dosimetry

    Background:

    • Endoscopic Retrograde Cholangiopancreatography (ERCP) and pneumo-colon examinations are common diagnostic procedures.
    • Accurate assessment of radiation dose is crucial for patient safety and risk evaluation in medical imaging.

    Purpose of the Study:

    • To compare the surface and organ radiation doses delivered during ERCP and pneumo-colon procedures.
    • To calculate somatic dose indices and evaluate individual and collective risks associated with these procedures.

    Main Methods:

    • Surface dose and scatter were measured using CaF2-thermoluminescence dosimetry during 50 ERCPs and 70 pneumo-colons.
    • Organ doses were calculated using an Alderson-Rando phantom for both procedures.

    Main Results:

    • Pneumo-colon examinations resulted in approximately 200 times the gonadal dose compared to ERCP.
    • Radiation exposure to the thyroid, lung, and female breast was lower during pneumo-colon procedures than ERCP.

    Conclusions:

    • The gonadal dose from radiological examination of the colon is substantially higher than from ERCP.
    • Risk-benefit analysis is essential, considering differential organ doses between ERCP and pneumo-colon procedures.
