The potential bioeffects associated with magnetic resonance (MR) procedures result from exposure to the static, gradient, and radiofrequency electromagnetic fields. Each electromagnetic field represents a possible health risk at sufficiently high levels of exposure. The presence of certain biomedical implants and devices may pose hazards for patients undergoing MR procedures. Additionally, other safety issues must be considered for patients in the MR environment. This review article discusses the bioeffects of MR exposures and provides an overview of safety considerations, with an emphasis on information pertinent to cardiovascular patients.
与磁共振(MR)检查相关的潜在生物效应源于暴露于静磁场、梯度磁场和射频电磁场。在足够高的暴露水平下,每个电磁场都代表一种可能的健康风险。某些生物医学植入物和设备的存在可能会给接受MR检查的患者带来危害。此外,对于处于MR环境中的患者,还必须考虑其他安全问题。这篇综述文章讨论了MR暴露的生物效应,并概述了安全注意事项,重点是与心血管疾病患者相关的信息。
