In Australia, recent data show there are over 80,000 computed tomography (CT) scans performed annually on children and young people under the age of 20.
CT is a valuable investigative technique because it provides a low risk, non-invasive, fast and accurate method of diagnosing serious injury and illness.
Doctors and other health care professionals who refer children and young people for CT scans should be aware of this risk and discuss it with the patient and the parent or carer.
- General information on scans, the possible risks for children and the importance of ordering the most appropriate imaging modality is available in the fact sheet CT scans and children: information for referrers.
- NPS MedicineWise also provides information for referrers on CT scans for children, including questions to consider.
- The Royal Australian and New Zealand College of Radiologists (RANZCR) has published resources to assist referrers of medical imaging, including:
- Position Statement: Computed Tomography and Radiation Risk (February 2018) that provides information on balancing the benefits and risks of CT scans and how the College is supporting quality use of CT.
- Inside Radiology that includes detailed advice on types of medical imaging for particular medical conditions.
- The National Institute of Health and Care Excellence (United Kingdom) clinical guidelines, Head injury: assessment and early management. These guidelines include clinical assessment algorithms for children who present to an emergency department with a head injury or cervical spine injury.
Clinical decision support tools
- The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) has developed an online learning module, Radiation Protection of the Patient for referrers of medical imaging. Australian GPs who complete the module may be able to earn CPD points for undertaking the training.
- The Western Australian Department of Health has developed a clinical decision support tool and educational resource for diagnostic imaging, WA Diagnostic Imaging Pathways. This resource has been endorsed by RANZCR.
- RANZCR has developed Education Modules for Appropriate Imaging Referrals which are designed for use in a health professional’s early career. The modules include detailed explanations of the evidence base, providing the background to, and demonstrating the appropriate use of, clinical decision rules.
