The literature within the last 10 years on MRI use in patients with orthopedic implants is reviewed. A literature search returned 15 relevant articles. Only 2 discussed pediatric patients. Overall, significant displacement of implants was infrequent. Radiofrequency-induced heating of implants differed among the studies, but most reported increases of less than 1°C. The authors conclude MRI is safe in patients with orthopedic implants because implant displacement and heating pose little risk to patients. A risk-to-benefit ratio is warranted, however, to assess the clinical utility and necessity of the study. Further research and individual assessment of implant properties and MRI-related interactions are warranted.
回顾了过去10年中关于在有骨科植入物患者中使用MRI的文献。文献检索得到了15篇相关文章。只有2篇讨论了儿科患者。总体而言，植入物的显著移位并不常见。各研究中植入物的射频感应加热情况有所不同，但大多数报告升温幅度小于1°C。作者得出结论，MRI对有骨科植入物的患者是安全的，因为植入物移位和加热对患者造成的风险很小。然而，有必要权衡风险与收益，以评估该研究的临床实用性和必要性。有必要进行进一步的研究以及对植入物特性和MRI相关相互作用进行个体评估。
