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.

再探討小兒CT掃描的輻射防護
劉丹、孔碧蘭
近年醫療成像技術不斷進步，使對病人的治療有了顯著改善，但同時令病人有機會暴露於輻射中，尤其是包括CT掃描在內相對較高劑量的成像技術。普遍認為暴露於輻射環境下的兒童產生病患的風險比成人高。本文重溫放射防護的一般原則，並提供有關小兒CT掃描的資料更新及作重點討論。
