Historically, the presence of cardiac implantable electronic devices (CIEDs), including pacemakers and implantable cardioverter defibrillators (ICDs), was widely considered an absolute contraindication to magnetic resonance imaging (MRI). The recent development of CIEDs with MR Conditional labeling, as well as encouraging results from retrospective studies and a prospective trial on the safety of MRI performed in patients with CIEDs without MR Conditional labeling, have led to a reevaluation of this practice. The purpose of this report is to provide a concise summary of recent developments, including practical guidelines that an institution could adopt for radiologists who choose to image patients with CIEDs that do not have MR Conditional labeling. This report was written on behalf of and approved by the International Society for Magnetic Resonance in Medicine (ISMRM) Safety Committee. LEVEL OF EVIDENCE: 3. TECHNICAL EFFICACY STAGE: 1.
从历史上看，心脏植入式电子设备（CIEDs）的存在，包括起搏器和植入式心律转复除颤器（ICD），被广泛认为是磁共振成像（MRI）的绝对禁忌证。具有磁共振条件性标签的 CIED 的最新发展，以及对没有磁共振条件性标签的 CIED 患者进行 MRI 的回顾性研究和前瞻性试验的令人鼓舞的结果，导致对这一做法进行了重新评估。本报告的目的是提供最近发展的简要总结，包括放射科医生在选择对没有磁共振条件性标签的 CIED 患者进行成像时可以采用的实用指南。本报告代表并经国际磁共振医学学会（ISMRM）安全委员会批准。证据水平：3。技术功效阶段：1。
