Time varying magnetic gradient fields can induce electric field (E-field) in the human body and may cause peripheral nerve stimulation (PNS) during MR scan. As metallic implant may cause local E-field enhancement, there is speculation that it may increase risk of PNS. In this study, gradient coil modeling is used to investigate induced E-fields around implantable devices. The maximum E-field in the proximity of implants is compared to the whole body maximum E-field of the human body without implant. The result shows that the local enhanced E-field near implants does not exceed the whole body maximum E-field in human body.
