Radiology During Pregnancy

Pregnancy is not a reason to avoid every radiology exam, but it does call for special consideration. The fetus is sensitive to radiation, especially in the first trimester, so communication with your doctor is essential.

Radiation risk to the fetus

Radiation doses from chest and dental X-rays are generally very small and are not considered to meaningfully increase risk to the fetus. However, higher-dose exams, especially those involving the abdomen and pelvis, call for more serious consideration.

Where feasible, abdominal shielding may be used during exams that do not involve that area, although this is not always appropriate for every procedure.

Alternative options

Ultrasound is the primary choice in pregnancy because it uses no radiation. MRI is also relatively safe, although gadolinium-based contrast is usually avoided during pregnancy unless truly necessary.

Your doctor will assess whether these alternatives are sufficient to answer the clinical question.

What you should do

Always tell staff and your doctor about pregnancy or possible pregnancy, even if you are not certain. This helps the team adjust the exam.

Do not postpone an important exam that is needed for your health. The best decisions are made together with your obstetrician and the radiology team.

Key points

• Tell staff before the exam.
• Ultrasound or MRI are often alternative options.
