Alder Hey's Radiology Department offers a number of different servicesThe Radiology Department works closely with other departments and services at Alder Hey to offer a range of scanning and imaging services.

Examples of these services include:


An x-ray, also called a radiograph, is carried out by a radiographer. We have three x-ray rooms at Alder Hey and we have male and female radiographers who are specially trained to work with children.

If you or your child would like a copy of the x-ray, you can buy a special education pack that includes a paper copy of the x-ray, as well as some information and activities about x-rays.


This is a different type of x-ray and is usually taken by a Consultant Radiologist with the help of a radiographer. Please note if you are bringing your child for a fluoroscopy, they may need to miss breakfast before coming to the hospital and when you get here, they may have to drink a special dye which shows up on x-rays.

You are able to stay with your child during a fluoroscopy test.


A CT scan uses a machine to take a more detailed image than you might see with an x-ray. Sometimes, we may need to give your child an injection of a special dye that makes the images even clearer but we use a ‘magic cream’ to numb the skin beforehand.

You are able to stay with your child during a CT scan.


An MRI scan uses a strong magnetic field, so it’s important that when your child goes into the scanning room, they don’t have anything made from metal on them or in their pockets.

We have two MRI scanners at Alder Hey. One is in the Radiology Department and the other is a special version which can be used in theatre to scan patients during operations.

An MRI scan takes a longer than other scans but patients can watch a film or listen to music to help them relax. If your child is too young or unwell to be able to lie still during an MRI scan they may need a general anaesthetic.


Ultrasound scans are usually performed by a radiographer or sonographer. All the radiographers and sonographers at Alder Hey are specially trained to work with children. We mostly use ultrasound to scan the stomach, but we can use it to scan any part of the body.

Ultrasounds are painless but to get the clearest pictures we need to use a jelly on your child’s skin, which they might find cold and sticky.

Nuclear Medicine

When your child comes to a nuclear medicine test they usually need to have an injection of a radioisotope, which is a special liquid that can be detected by a gamma camera. We use a ‘magic cream’ to numb your child’s skin before the injection and our radiographers are all specially trained to work with children.

Depending on the area we need to look at, we may do the scan immediately after the injection but in some cases we may need to wait a few hours.


We use the DEXA scanner to check bone density and check if bones are fragile or if they are at risk of fracturing.
