On a possible mechanism for peripheral nerve stimulation during magnetic resonance imaging scans
journal contribution
posted on 2023-05-16, 12:44 authored by Lawrence ForbesLawrence Forbes, Crozier, SWhen patients undergo a magnetic resonance imaging scan, they are subject to both strong static and temporal magnetic fields. The temporal fields are designed to vary at each point in the region being imaged. This is achieved by the use of gradient coils. However, when the gradient coils are switched very rapidly, the strongly time-varying magnetic fields produced cqn be responsible for stimulating nerves in the peripheral regions of the body. This paper gives a somewhat novel explanation for this phenomenon. The physical mechanism suggested is supported by an illustrative theoretical calculation.
