摘　　要：磁共振成像技术的飞速发展使得磁共振扫描成为一种常规甚至不可或缺的影像检查,临床上各种各样体内植入物也已经成为一种常规的治疗手段。面对越来越多体内植入物患者的磁共振检查申请,迫切需要对于体内植入物相关磁共振扫描安全问题进行澄清。本文就常见不同类型体内植入物的磁共振扫描给出辨证合理的安全建议,磁共振扫描安全首先要求严格细致的患者筛查,对于体内植入物患者需要进一步搞清植入物类型、植入时间、植入物位置等细节;然后根据植入物类型以及检查部位对执行扫描的风险和该检查对病人的帮助进行综合评估,区别对待;执行扫描时还需要采用针对性的扫描序列,将风险降到最低。With the rapid development of magnetic resonance （MR） imaging technology over the past two decades, MR scan have become an increasingly attractive imaging modality. With the growing number of patients treated with permanent implanted or temporary cardiovascular devices, it is more important to clarify safety issues in regard to the performance of MR examinations in patients with these devices. Safe MR imaging demands careful initial patient screening, and identifies type, time and position of implant. Then different treatment is needed with comprehensive assessment of scanning risk and the help for patients. It also needs to adopt specific sequence to minimize risk.
