Guide | Are X-Rays Safe During Pregnancy? Experts Answer Key Questions
X-rays during pregnancy raise concern because radiation may adversely affect the fetus and could even cause birth defects. Medical needs may nevertheless require an X-ray during pregnancy, such as confirming a fracture after an accidental injury. Do X-rays really affect pregnancy, and how can potential risks be reduced?
Radiation risks of X-rays during pregnancy
X-rays are ionizing electromagnetic radiation with wavelengths between ultraviolet light and gamma rays. Although many people worry about radiation, medical X-ray doses are far below exposure levels from the nuclear explosions of World War II. Evidence indicates that a single X-ray of an arm, leg, or tooth has minimal fetal effects and is generally safe.
During pregnancy, the mother's abdominal wall and uterus block most radiation from reaching the fetus. Even so, cumulative exposure from repeated X-rays may increase the risks of fetal growth restriction, abnormalities, impaired brain function, or cancer. Although these risks are low, high-dose radiation exposure should be particularly avoided between weeks 10 and 17 of pregnancy.
Which X-rays are safer for the fetus?
X-rays of the arms, legs, head, teeth, and chest are generally safe during pregnancy because they do not directly expose the abdomen. X-rays of the abdomen, pelvis, kidneys, or lower back expose the fetus to radiation and are generally avoided.
High-dose imaging such as a CT scan early in pregnancy may increase the child's cancer risk. Tests involving higher radiation doses, such as a barium enema, are unsuitable during pregnancy and should be avoided.
How can the fetus be protected during an X-ray?
Anyone who needs an X-ray during pregnancy must tell the doctor. Precautions can then be tailored to the stage of pregnancy and the patient's health. If the examination is not urgent, it may be postponed until after delivery. For imaging of the arms, legs, head, or neck, a lead apron is usually provided to shield the fetus. **Ultrasound and magnetic resonance imaging (MRI)** are also commonly used alternatives that do not involve ionizing radiation.
Is an accidental X-ray during pregnancy harmful?
If an abdominal X-ray was performed before the pregnancy was known, tell the doctor promptly. A single X-ray uses a low radiation dose and usually does not seriously affect the fetus. After high-dose procedures, such as CT or X-ray guidance during cardiac or orthopedic surgery, consult a doctor to assess potential risks.
To prevent accidental exposure, some hospitals perform pregnancy tests before relevant examinations for all females aged 12 and older.
X-rays during pregnancy: caution, not panic
Although X-rays are preferably avoided during pregnancy, modern equipment uses low radiation doses, and one X-ray generally does not harm the fetus. Doctors weigh the risks of imaging against the health risks of not performing it. The fetus is generally more sensitive to radiation before week 18, while after week 26 its sensitivity is close to that of a newborn. When medically necessary, an X-ray can be a reasonable measure to protect maternal and fetal health.
