Although magnetic resonance (MR) imaging does not use ionizing radiation, it has its own safety issues. MR safety concerns are associated with the static magnetic field, radiofrequency burns, scanner acoustic noise, and the use of gadolinium-based contrast agents. MR technologists have a responsibility to thoroughly screen patients and personnel before they enter the magnetic field and to research patient implants and devices to determine under what conditions the patient can be scanned safely. During long scans, MR technologists also must monitor patients to avoid adverse events. This article is useful for non-MR technologists who might work in the MR environment or who are considering cross-training in this important discipline.
虽然磁共振成像（MR）不使用电离辐射，但它也有其自身的安全问题。MR 安全问题与静磁场、射频灼伤、扫描仪声噪声以及钆基造影剂的使用有关。MR 技术人员有责任在患者和人员进入磁场之前对其进行彻底筛查，并对患者的植入物和设备进行研究，以确定在何种情况下可以安全地对患者进行扫描。在长时间扫描过程中，MR 技术人员还必须对患者进行监测，以避免发生不良事件。本文对于可能在 MR 环境中工作或考虑在这一重要学科中交叉培训的非 MR 技术人员非常有用。
