MRI is used widely in infants and young children. However, in these young cases deep sedation or general anesthesia is often required to minimize motion artifacts during MRI examinations. Although the benefits of MR typically outweigh the potential risks of sedation when delivered by an experienced team, there are increasing concerns regarding the affect of sedation on young children. There continues to be a push to develop various strategies that can minimize the need for sedation. The present review summarizes several technical and clinical approaches that can help decrease the need for sedation in the pediatric patient. Optimization of the MRI environment, the role of child life specialists, feed-and-bundle and distraction techniques, noise-reduction methods, artificial intelligence, and MRI advances to decrease both scan times and motion artifacts will be discussed.

MRI 在婴儿和幼儿中广泛应用。然而，为了最大限度地减少 MRI 检查过程中的运动伪影，这些年幼的患者通常需要深度镇静或全身麻醉。尽管由经验丰富的团队进行镇静时，MR 的益处通常超过潜在风险，但越来越多的人关注镇静对幼儿的影响。人们一直在努力开发各种策略，以尽量减少镇静的需求。本综述总结了几种可以帮助减少儿科患者镇静需求的技术和临床方法。优化 MRI 环境、儿童生活专家的作用、喂养和捆绑以及分散注意力的技术、降噪方法、人工智能以及减少扫描时间和运动伪影的 MRI 进步等都将进行讨论。证据水平：5 技术功效阶段：1 J. 磁共振成像 2019 年。
