Radiation Protection in Paediatric Computed Tomography Revisited

Advances in medical imaging have been exponential in recent years, resulting in significant improvements to patient care. This has also incurred an increase in radiation exposure for patients, primarily due to the increased use of relatively high radiation dose imaging modalities, namely computed tomography. It is widely recognised that children are generally at higher risk of the adverse effects of radiation than adults. This article revisits the general principles of radiological protection, and provides updates and highlights of the practice in paediatric computed tomography.
