Magnetic resonance (MR) imaging relies on a strong static magnetic field in conjunction with careful orchestration of pulsed linear gradient magnetic fields and radiofrequency magnetic fields in order to generate images. The interaction of these fields with patients as well as materials with magnetic or conducting properties can be a source of risk in the MR environment. This article provides a basic review of the physical underpinnings of the primary risks in MR imaging to foster development of intuition with respect to both patient and risk management in the MR environment.
磁共振（MR）成像是基于强静磁场，结合线性脉冲梯度磁场和射频磁场的精细调控，以生成图像。这些磁场与患者以及具有磁性或导电性的材料相互作用，可能会成为 MR 环境中的风险源。本文对 MR 成像中主要风险的物理基础进行了基础回顾，以培养对 MR 环境中的患者和风险管理的直觉。
