An X-ray is a type of imaging test – a test that uses special equipment to create detailed images of part of the inside of the body, including organs like the kidneys.
What is an X-ray test?
An X-ray test uses X-rays to take a picture of your child’s bones and other parts of the inside of their body. Denser structures (such as bones) look white in the image, and softer structures (such as the heart) look a bit darker.
Why does my child need this test?
X-ray tests may be used for different reasons. For example, a chest X-ray is used for children who have problems breathing, as it can show whether there is any fluid or infection in the lungs.
Are X-ray tests safe?
X-ray tests are considered safe.
X-rays are a type of ionising radiation - a form of energy. We’re all exposed to low levels of radiation every day – it comes from sources including building materials and some foods.
When your child has an X-ray scan, they receive the amount of radiation they’d be exposed to naturally in around 3 months.
Your doctor will carefully consider the risks and benefits of using an X-ray test in your child.
Where will it take place?
X-ray tests normally take place in the X-ray department of your hospital.
Who will perform the X-ray test?
A radiographer, a specialist trained in imaging tests, usually performs the test.
How to prepare your child for an X-ray
Your child does not usually need to do anything to prepare for this test, but your doctor will let you know.
Talk to your child about the test and what will happen. If they are old enough, explain what the test is looking for and why it is needed.
Older girls may be asked if they are having their period, and about the dates of their last period. They may also be asked if they are pregnant or if they could be pregnant. This is because ionising radiation from X-rays may harm an unborn baby.
The radiographer may ask your child to remove any metal objects, such as a watch, before the test starts.
