The number of medical X-ray imaging procedures is growing exponentially across the globe. Even though the overall benefit from medical X-ray imaging procedures far outweighs any associated risks, it is crucial to take all necessary steps to minimize radiation risks to children without jeopardizing image quality. Among the X-ray imaging studies, except for interventional fluoroscopy procedures, CT studies constitute higher dose and therefore draw considerable scrutiny. A number of technological advances have provided ways for better and safer CT imaging. This article provides an update on the radiation safety of patients and staff and discusses dose optimization in medical X-ray imaging within pediatric neuroradiology.
全球范围内，医学X射线成像检查的数量正在呈指数级增长。尽管医学X射线成像检查带来的总体益处远远超过任何相关风险，但在不影响图像质量的前提下，采取一切必要措施将儿童所受辐射风险降至最低至关重要。在X射线成像研究中，除介入性荧光透视检查外，CT检查的辐射剂量更高，因此受到了相当多的审视。多项技术进步为更好、更安全的CT成像提供了方法。本文介绍了患者和工作人员辐射安全方面的最新情况，并讨论了儿科神经放射学中医学X射线成像的剂量优化问题。
