Magnetic resonance (MR) imaging is a useful imaging tool with superior soft tissue contrast for diagnostic evaluation. The MR environments poses unique risks to patients and employees differently from ionizing radiation exposure originated from computed tomography and plain x-ray films. The technology associated with MR system has evolved continuously since its introduction in the late 1970s. MR systems have advanced with static magnetic fields, faster and stronger gradient magnetic fields and more powerful radiofrequency transmission coils. Higher field strengths of MR offers greater signal to noise capability and better spatial resolution, resulting in better visualization of anatomic detail, with a reduction in scan time. With the rapid evolution of technology associated with MR, we encounter new MR-related circumstances and unexpected dangerous conditions. A comprehensive update of our knowledge about MR safety is necessary to prevent MR-related accidents and to ensure safety for patients and staff associated with MR. This review presents an overview about MR-related safety issues and updates.
磁共振（MR）成像是一种有用的成像工具，具有出色的软组织对比度，用于诊断评估。与计算机断层扫描和平片X线摄影产生的电离辐射暴露不同，MR环境给患者和工作人员带来独特的风险。自20世纪70年代末引入以来，与MR系统相关的技术一直在不断发展。MR系统随着静磁场、更快更强的梯度磁场以及更强大的射频发射线圈而不断进步。更高场强的MR提供了更高的信噪比能力和更好的空间分辨率，从而能够更好地显示解剖细节，并缩短扫描时间。随着与MR相关技术的快速发展，我们遇到了新的与MR相关的情况和意外的危险状况。全面更新我们关于MR安全的知识对于预防与MR相关的事故以及确保与MR相关的患者和工作人员的安全是必要的。本综述介绍了有关MR相关安全问题及更新的概述。
