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 degrees 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.
