Introduction to X-rays in Pregnancy
Pregnancy can make routine medical decisions more complicated, including the use of X-rays. Many women wonder if X-rays are safe during pregnancy and whether they can affect the developing baby. According to Dr Bimalpreet Mohan, director and chief radiologist at Capital Health Clinic, pregnancy does not automatically mean that every X-ray or imaging examination must be avoided.
The decision to use an X-ray or other imaging test during pregnancy depends on several factors, including the type of examination, the part of the body being examined, and the amount of radiation involved. Dr Mohan emphasizes that doctors weigh the potential risks of imaging tests against the benefits of getting an accurate and timely diagnosis.
Location of the X-ray Matters
Not all X-rays expose the developing baby to the same amount of radiation. An examination of the chest, arm, leg, or head is very different from imaging that directly involves the abdomen or pelvis. For abdominal or pelvic examinations, the pregnancy and medical necessity of the test need to be considered carefully.
Dr Mohan explains that doctors may explore whether another appropriate imaging method can provide the required information. Ultrasound, which does not use ionising radiation, is commonly used during pregnancy, while MRI may also be appropriate in selected circumstances.
What if the Woman is Unaware of the Pregnancy?
Some women may undergo an X-ray before discovering that they are pregnant. In this situation, Dr Mohan advises women to inform their doctor rather than immediately assuming that harm has occurred. The actual exposure depends on the examination and the area of the body imaged, so the circumstances need to be reviewed individually.
Shielding and Radiation Protection
Radiation protection is an important part of radiology. Depending on the examination and local protocols, appropriate positioning, equipment settings, and protective measures may be used to minimise unnecessary exposure. Dr Mohan highlights that the larger principle is justification and optimisation: an examination should have a clear medical reason, and radiation exposure should be kept as low as reasonably achievable while still obtaining useful diagnostic information.
Ultrasound as an Alternative
Ultrasound is extremely useful during pregnancy, but it cannot answer every clinical question that an X-ray or another imaging examination can. Dr Mohan explains that each modality gives different information, and the right choice depends on what is being looked for and which test can answer that particular clinical question.

Implications for Readers in India
In India, access to imaging services may vary depending on the location and healthcare facility. However, it is essential for pregnant women to be aware of the options available and to discuss their concerns with their doctor. By being informed, women can make better decisions about their health and the health of their baby.
What to Watch Next
As medical technology continues to evolve, it is likely that new imaging modalities and techniques will become available. Pregnant women should stay informed about these developments and discuss their options with their healthcare provider.
Conclusion
Pregnancy should make women more informed about imaging, not fearful of it. Dr Mohan concludes that the aim is never to expose a pregnant woman unnecessarily, but delaying an important diagnosis can also carry risks. Imaging decisions during pregnancy should therefore be individualised, with the health of both mother and baby kept in mind.
