New implanted medical devices continue to be made available for treatment of medical conditions. Many recipients can benefit from the diagnostic power of MR imaging. Provisions must be made to determine if these patients can be safely scanned. Metal-containing devices can be considered either MR unsafe or conditional. It is essential that all components of an implanted system are completely and accurately identified, with the most restrictive MR safety condition dictating the scanning approach. MR safety considerations for major classes of implanted devices are discussed, recognizing that there have been reports of serious device-related MR safety incidents.
新的植入式医疗器械不断被用于治疗各种疾病。许多接受者可以受益于磁共振成像的诊断能力。必须确定这些患者是否可以安全地进行扫描。含金属的设备可被认为是磁共振不安全或有条件安全。重要的是，必须完整、准确地识别植入系统的所有部件，并根据最严格的磁共振安全条件来决定扫描方法。讨论了主要类别植入式设备的磁共振安全注意事项，同时认识到已有关于严重与设备相关的磁共振安全事件的报告。
