Electromagnetic fields arising from magnetic resonance imaging (MRI) can cause various clinically relevant functional disturbances in patients with cardiac pacemakers. Consequently, an implanted pacemaker is generally considered a contraindication for an MRI scan. With approximately 60 million MRI scans performed worldwide per year, MRI may be indicated for an estimated majority of pacemaker patients during the lifetime of their pacemakers. The availability of MR conditional pacemakers with CE labelling is of particular advantage since they allow the safe use of pacemakers in MRI. In this article the current state of knowledge on pacemakers and MR imaging is discussed. We present the results of a survey conducted among Swiss radiologists to assess current practice in patients with pacemakers.
磁共振成像（MRI）产生的电磁场会导致心脏起搏器患者出现各种临床相关的功能障碍。因此，植入式起搏器通常被认为是 MRI 扫描的禁忌症。全球每年约进行 6000 万次 MRI 扫描，在起搏器患者的一生中，估计大多数患者都需要进行 MRI。具有 CE 标记的 MR 条件起搏器的可用性具有特别的优势，因为它们允许在 MRI 中安全地使用起搏器。本文讨论了起搏器和磁共振成像的现有知识状态。我们展示了一项在瑞士放射科医生中进行的调查结果，以评估起搏器患者的当前实践情况。
