Abstract

Children's cells are more sensitive to the effects of radiation than those of adults. Therefore, selecting age- and weight-specific protocols is more appropriate than applying adult protocols to pediatric patients. Diagnostic Reference Levels (DRLs) are an effective tool for adjusting radiation doses in pediatric computed tomography (CT) scans to ensure that the doses are within acceptable levels and that the image quality is sufficient for diagnostic purposes, in accordance with the principle of radiation protection to prevent unnecessary harm to the patient. DRLs are not dose limits, but they can be adjusted up or down to match the required image quality. Another important benefit of DRLs is their use as a benchmark for comparing against national radiation reference levels or other international standards, and applying them in the process of radiation dose optimization. The purpose of this article is to provide guidelines for adjusting appropriate radiation doses, especially for pediatric patients.
