Understanding X-Rays and Radiation
X-rays use a small amount of ionising radiation to create images of bones and tissues. The dose used in most diagnostic X-rays is very low, and the risk to a developing baby is generally small. However, because radiation exposure carries a theoretical risk, especially in early pregnancy, healthcare professionals take a cautious approach and only recommend X-rays when the benefits clearly outweigh any potential harm.Dental X-Rays During Pregnancy
Dental X-rays use extremely low doses of radiation and are considered safe during pregnancy when properly shielded. If you need routine dental work, let your dentist know you are pregnant. They may postpone non-urgent X-rays until after birth, but if you have an infection or toothache, the risk of leaving it untreated can be greater than a single X-ray. A lead apron placed over your abdomen provides additional protection.Medical X-Rays and Scans
If you need an X-ray for a medical reason, such as a suspected fracture or chest infection, tell the radiographer you are pregnant. They will assess whether the scan is essential and use the lowest possible dose. CT scans involve higher doses and are only used in pregnancy when absolutely necessary. Ultrasound and MRI scans do not use ionising radiation and are the preferred imaging methods during pregnancy.When X-Rays Are Necessary
Sometimes an X-ray is the best way to diagnose a serious problem, and delaying treatment could pose a greater risk to you and your baby. In emergencies, such as suspected pneumonia or a serious injury, your care team will weigh the risks carefully and use shielding where possible. The decision is always individualised, so ask your healthcare provider to explain the benefits and risks in your specific situation.FAQ
### Can I have an X-ray while pregnant?Yes, if it is medically necessary. The dose used in most diagnostic X-rays is low, and shielding protects your baby. Always tell the radiographer you are pregnant.
Are dental X-rays safe during pregnancy?
Dental X-rays use very low radiation doses and are safe with abdominal shielding. Dentists often postpone routine X-rays but will treat urgent problems promptly.
Do ultrasound scans use radiation?
No. Ultrasound uses sound waves, not ionising radiation, so it is considered safe throughout pregnancy. MRI also does not use ionising radiation.
