MDCT的引入增加了CT在儿科放射学中的使用，沿着对辐射后遗症的关注。本文综述了降低辐射剂量的一般原则，影响辐射剂量的基本物理学，以及针对儿科人群的特定CT综合剂量降低工具。本文的目的是提供一个全面的审查最近的文献CT剂量减少的方法，其局限性，并展望未来的发展，重点是儿科人群。讨论将首先侧重于导致辐射剂量减少的一般考虑因素，然后是影响辐射剂量的具体技术特征。
The introduction of MDCT has increased the utilization of CT in pediatric radiology along with concerns for radiation sequelae. This article reviews general principles of lowering radiation dose, the basic physics that impact radiation dose, and specific CT integrated dose-reduction tools focused on the pediatric population. The goal of this article is to provide a comprehensive review of the recent literature regarding CT dose reduction methods, their limitations, and an outlook on future developments with a focus on the pediatric population. The discussion will initially focus on general considerations that lead to radiation dose reduction, followed by specific technical features that influence the radiation dose.
