RF heating causes most of incidents during MRI examinations. There still are patients who were implanted metallic products before the advent of MRI and MR compatibility of most such products is unknown. It was reported that an MRI examination of a patient implanted an intramedullary rod in his forearm was aborted due to a heating claim from the patient. In this study, we confirm RF heating of such patient by using an electromagnetic analysis software dedicated for MRI, and shows that positioning of an implanted arm can decrease SAR sufficiently enough to take MRI examinations.
