Core Tip
Core tip: Computed tomography (CT) delivers substantially radiation dose and risk of cancer than alternative imaging methodologies, particularly in children, and use of paediatric CT scans is increasing. Radiation exposure from CT scanning can be minimized by eliminating multiple or medically unnecessary scans, patient-specific dosing guidelines, and use of other radiographic methods where appropriate; however, medical practitioners’ lack of awareness of CT dose and its potential dangers are also important. Improvements to CT protocols, referral practices and imaging professionals’ education are needed to minimise unnecessary CT radiation exposure in children.
