Magnetic resonance-guided radiation therapy is reported for treating patients with an insertable cardiac monitor and implantable cardiac pacemakers. All treatments were delivered using a 1.5 T MR-Linac. Among the 4 patients, 2 were treated with stereotactic body radiation therapy at a dose of 40 Gy in 5 fractions. A clinical safety protocol was developed to address the decision-making and patient selection, as well as the clarified responsibilities of different parties for management of patients with cardiovascular implantable electronic devices. Dose estimation based on out-of-field dose data are necessary for cardiovascular implantable electronic devices located outside the treatment fields.

据报道，磁共振引导的放射疗法可用于治疗具有可插入心脏监视器和可植入心脏起搏器的患者。所有治疗均使用 1.5 T MR-Linac 进行。4 例患者中，2 例接受立体定向放射治疗，剂量为 40 Gy，分 5 次进行。制定了临床安全协议，以解决决策和患者选择问题，以及明确各方对心血管植入式电子设备患者管理的责任。基于场外剂量数据的剂量估计对于位于治疗场外的心血管植入式电子设备是必要的。
