With more and more 3 Tesla high-field magnetic resonance (MR) scanners entering clinical routine, the safety notion in MR imaging has also reached a new dimension. The first part of this paper deals with the three most important sources of physical interaction (static magnetic field, gradient and HF fields). The paper discusses the differences compared with the traditional clinical 1.5 T standard scanners, the impact on human beings, the interactions with metallic objects and the relevant safety standards. The second part of the paper examines the issue of MR safety as seen in clinical practice and tries to demonstrate optimization potentials. This includes structural optimization in information distribution and hospital organization as well as test standards and labeling guidelines.
随着越来越多的3特斯拉高场磁共振（MR）扫描仪进入临床常规使用，MR成像中的安全概念也达到了一个新的层面。本文的第一部分探讨了物理相互作用的三个最重要来源（静磁场、梯度场和高频场）。本文讨论了与传统临床1.5T标准扫描仪相比的差异、对人体的影响、与金属物体的相互作用以及相关的安全标准。本文的第二部分研究了临床实践中所见的MR安全问题，并试图展示优化潜力。这包括信息传播和医院组织方面的结构优化以及测试标准和标签指南。
