Computational modeling reveals reduced peripheral nerve stimulation thresholds near orthopedic plates under MRI gradient fields, highlighting safety risks for patients with implants.
Orthopedic implants can substantially lower the activation thresholds of nearby nerves, with some thresholds approaching the PNS limits defined in IEC 60601-2-33 for MRI gradient field. This finding indicates a reduced safety margin for patients with implants, highlighting the need for more comprehensive safety assessments.
