X-ray Examinations during pregnancy

​We will need to know your pregnancy status if you are a woman aged between 9 to 60 years old, as there is a possibility that you may be pregnant.

X-rays or ionizing radiation poses a risk to the unborn baby.

There may be an increased risk of birth defects, cancers and certain diseases to the unborn baby when exposed to ionizing radiation. The risk will depend greatly on the type of examination and any measures taken to reduce the exposure.

Examinations that use ionizing radiation are:

  • X-rays or radiographs (e.g, chest X-Ray, Abdominal X-Ray, X-Ray of bones)
  • CT scan (e.g. CT brain, CT Abdomen/Pelvis, CT Urogram, CT Angiogram)
  • Fluoroscopy (Barium Meal, Barium Swallow, Cholangiogram)
  • Mammography or Mammograms
  • Nuclear Medicine scans (e.g. PET CT, Bone scan)

Incidents do happen

There have been cases where patients thought they were not pregnant but found to be pregnant after the examination. That caused great anxiety and stress for the parents-to-be.

As such, always approach any of our staff or doctor if you are unsure of your pregnancy status or think you may be pregnant.
