Nazarian et al. recently studied the safety of magnetic resonance imaging in a large cohort of patients with cardiac devices not considered to be MRI-conditional (termed a "legacy" device). More than 2100 thoracic and nonthoracic MRI examinations were performed in 1509 patients. It was found that with appropriate precautions, including a prespecified safety protocol, no long-term clinically significant adverse events occurred. It could easily be concluded from these observations that MRI can now be considered "safe" in this category of patients. Whether such a conclusion is justified, is questionable however. Although not life-threatening, interactions between MRI and devices still occur and clinical consequences remain unpredictable. It is therefore strongly recommended that MRI in patients with a legacy device should exclusively be performed in centres of excellence. Only in the presence of a multidisciplinary radiological and cardiac expert team can MRI be conducted with acceptable risks in patients with a legacy device.
纳扎里安等人最近在一大群使用非磁共振成像（MRI）条件适用型心脏设备（即“传统”设备）的患者中研究了MRI的安全性。对1509名患者进行了2100多次胸部和非胸部MRI检查。结果发现，采取适当的预防措施，包括预先制定的安全方案后，未发生长期具有临床意义的不良事件。从这些观察结果很容易得出结论，即现在可以认为MRI对这类患者“安全”。然而，这样的结论是否合理，是值得怀疑的。虽然MRI与设备之间的相互作用不会危及生命，但仍会发生，且临床后果仍然不可预测。因此，强烈建议，对使用传统设备的患者进行MRI检查应仅在卓越中心进行。只有在多学科放射学和心脏专家团队在场的情况下，才能在使用传统设备的患者中进行MRI检查，且风险可接受。
