CT scan information for parents and carers
CT scans and radiation exposure in children and young people
The Australian Commission on Safety and Quality in Health Care (the Commission) is promoting new and existing resources to inform the referral and provision of CT scans for children and young people. Assisted by a number of partners, the Commission’s work supports a reduction in unwarranted radiation exposure to children and young people. The Commission has published a summary report on the outcomes of their work to reduce radiation exposure to children and young people from CT scans.
What is a CT scan?
A computed tomography (CT) scan uses X-rays to provide images of what is hard and soft inside a body. These X-rays are taken using a rotating ring that is moved around the body. A computer can then turn all the X-ray images into 3D images. As CT scans involve many X-rays, they use higher levels of ionising radiation than other types of medical imaging.
Children and young people and CT scans
CT is a valuable diagnostic tool that is of benefit in a wide range of clinical situations. However, the higher level of ionising radiation used in CT compared to other types of imaging, and their use in childhood or adolescence, has been linked to a slight increase in developing cancer later in life.
It is important to ensure that CT scans are undertaken for time-critical conditions and when there are evidence-based protocols for a particular disease or certain conditions (such as, serious head trauma). However, children and young people are more sensitive to ionising radiation as their bodies are still developing. This means that appropriate consideration needs to be given to whether:
- a CT scan now will improve the child’s health care
- previous scans are available that could provide the information needed
- there are other imaging options that could be used
- a necessary CT scan be done using a ‘kid-sized’ radiation dose
- the benefits and risks have been explained to the parents or carers.
The following pages provide access to information for parents and carers, professionals who refer children for CT scans, providers of medical imaging services and oral healthcare professionals.

What parents should know about CT scans for children | ARPANSA
A CT scan is an X-ray imaging technique that is used on people of all ages, including children. CT scans are vitally important for quickly investigating serious health problems inside the body, for example, bleeding inside the skull after a fracture. CT scans provide more information than a plain X-ray image.

CT scans for children: Information for referrers | ARPANSA
CT scans are a valuable investigative technique because it provides a low risk, non-invasive, fast and accurate method of diagnosing serious injury and illness. However, all these benefits come with an increased exposure to ionising radiation which has been linked to an increased risk of cancer.

Screening for lung cancer | Cochrane
Lung cancer is the most common cause of cancer-related death in the western world. It takes about 20 years to develop and cigarette smoking is a known cause. Most lung cancers are not found early in the development of the disease. Regular screening is offered to those considered to be at high risk of contracting the disease. Trials were made of early detection methods such as the testing of sputum, x-ray and computed tomography (CT) scanning of the chest to see whether they made a difference to the number of people who were treated by surgery and the number of people who died as a result of the disease. This review examined the evidence from nine trials (with a total of 453,965 participants) and found that early screening with chest X-ray or sputum testing does not reduce the number of people who die from lung cancer. Screening with low-dose chest CT was found in one large trial to reduce the number of people who die from lung cancer but this trial only included very high-risk smokers and ex-smokers. CT screening however is associated with a high number of false positive results and there are also some people who have lung cancer detected and treated but in whom this cancer may not have progressed to cause death in their lifetime, even in the absence of treatment (referred to as overdiagnosis). More research is needed about the relative harms and benefits of CT screening in individuals at lower risk for lung cancer.
