An X-ray is a picture which is taken using a form of radiation that is able to pass through the body to create a digital X-ray image. Different parts of the body contain different tissues, which vary in how much X-ray radiation they absorb (depending on how dense they are). When the X-rays
pass through the body, they create an image like a shadow. This means bones, soft tissues and air, for example, can be seen on the X-ray images in white, shades of grey, and black.
X-rays are performed for many different reasons, including to:
Having an X-ray does not hurt, but in some cases, the position your child needs to be in for the X-ray may be uncomfortable. Your child will need to be still while the X-ray image is being taken.
Your child may be asked to change into a hospital gown before the X-ray exam. If they would prefer not to wear the hospital gown, wearing a plain T-shirt and shorts or leggings may be OK. Articles of clothing may have to be removed if they contain decoration, metal, glitter, thick elastic, string
ties or plastic that may show up on the X-ray images and make important body structures difficult to see. Long hair needs to be tied up for neck and chest examinations, and nappies will be removed for all hip and pelvis examinations.
Patients who use a wheelchair may need to be moved onto a special chair for the examination to prevent the metal parts of the wheelchair showing up on the image.
A parent or carer is encouraged to stay with their child to help them feel comfortable about the procedure and to help them to remain still for their X-ray. Please let the technologist know if you are or may be pregnant – this will remain completely confidential. You will be able to remain with
your child during all procedures.
The time it takes to perform the X-ray examination depends on how many images are required, but it may be as little as five minutes.
The requirements for your child's X-ray will depend on the body part that is being examined:
A report will be prepared by the Radiologist and sent to the referring doctor. The report is usually available within a few days but can be received earlier if required. If you have any questions about why your child needs an X-ray, or questions about the results of your X-ray, please speak to your doctor.
My child is anxious about medical procedures and I am worried they won't stay still for the X-ray. How can I help?
To get some ideas of how to talk to your child about the scan before you come to hospital, see our fact
sheet. Also consider showing your child our
‘Be Positive’ videos of children having procedures at The Royal Children's Hospital (RCH). Seeing the videos may help them by knowing what to expect. You can also download our
Okee in Medical Imaging app, which includes games and information especially designed to help children feel more comfortable about having medical imaging at RCH.
Specialist staff from
Child Life Therapy may also be of benefit for your child – appointments can be made in advance via Medical Imaging or your referring doctor.
Will I need to wear a lead apron during the X-ray?
You may be required to wear a lead apron if you remain with your child during their X-ray.
How safe are X-rays for children? If my child needs more than one X-ray is this dangerous?
All medical imaging procedures at RCH have been justified by a Radiologist or Specialist before the exam is performed. All imaging procedures are optimised – each study is performed with the aim to provide the highest quality imaging with the lowest radiation dose to each
For more information on radiation, please see the Australian Government fact sheet:
Ionising Radiation and Health, or speak to your radiographer.
