Peripheral nerve stimulation is a typical source of concern in MRI, which, in principle, could be significantly affected by the presence of a foreign object, like an orthopaedic prosthesis, in the body. This work investigates this possibility through a computational approach, making use of a human model where a knee implant has been placed, realistically, through a “virtual surgery”. Results indicate that the presence of the prosthesis can give rise to local enhancement of the electric field induced by the operation of the gradient coils, hence increasing the risk.
