Radiation risks in pregnancy.

K L Mossman, L T Hill

    Obstetrics and Gynecology
    |August 1, 1982
    PubMed
    Summary

    Radiodiagnostic procedures during pregnancy, particularly abdominal X-rays in the first trimester, typically result in low embryonic radiation doses. These radiation risks are generally considered small compared to other pregnancy risks.

    Area of Science:

    • Radiology
    • Obstetrics
    • Radiation Oncology

    Background:

    • Pregnancy is a major contraindication for radiodiagnostic procedures.
    • Approximately 1% of pregnant women undergo abdominal X-rays, often in the first trimester.
    • Assessing radiation exposure requires evaluating examination type, timing, dose, and risk.

    Purpose of the Study:

    • To evaluate the risks associated with radiodiagnostic procedures during pregnancy.
    • To determine typical radiation doses to the embryo from X-ray examinations.
    • To discuss methods for minimizing fetal radiation exposure.

    Main Methods:

    • Review of radiodiagnostic procedures performed on pregnant women.
    • Estimation of radiation doses to the embryo.
    • Comparison of radiation risks with other pregnancy-related risks.

    Main Results:

    • Radiation exposures typically result in embryonic doses below 5 cGy (rad).
    • The radiation risks associated with these doses are generally small.
    • Various procedures to minimize fetal exposure were considered.

    Conclusions:

    • Diagnostic X-rays during pregnancy, when evaluated carefully, often pose minimal risk.
    • Risk-benefit analysis is crucial when considering radiodiagnostic procedures in pregnant patients.
    • Minimizing radiation exposure to the fetus is an important consideration.
