Magnetic resonance imaging (MRI) has become a commonly used non-ionizing radiation dependent imaging modality which has an excellent spatial resolution with the capability to provide physiological information. Cardiac implantable electronic devices (CIEDs) are used in modern cardiology with a frequency of 1:50 over 75 years of age and nearly one in three people in this population required MRI during their lifetime. Changes in the CIED structure, electronics, and algorithms paired with changes in the protocol design of MRI have created a relatively safe environment for performing MRI in patients with CIED. Despite their documentation in literature and a guideline document from a professional society, significant skepticism exists in doing MRI in patients with CIEDs. We intend to give an overview of interactions between MRI and CIEDs, including the evidence available in this regard and conclude with the suggestion of a protocol for safely carrying out an MRI in patients with CIEDs.
磁共振成像（MRI）已成为一种常用的非电离辐射依赖成像方式，具有出色的空间分辨率，并能够提供生理信息。心脏植入式电子设备（CIEDs）在现代心脏病学中应用广泛，在 75 岁以上人群中的频率为 1:50，几乎每三个人中就有一个人在其一生中需要进行 MRI。CIED 的结构、电子设备和算法的变化，以及 MRI 协议设计的变化，为在 CIED 患者中进行 MRI 创造了相对安全的环境。尽管在文献和专业学会的指南文件中有相关记录，但在对 CIED 患者进行 MRI 检查方面仍存在很大的怀疑。我们旨在概述 MRI 与 CIED 之间的相互作用，包括这方面的现有证据，并提出一个安全进行 CIED 患者 MRI 的方案建议。
