The eddy currents induced by the RF magnetic field B1 due to the presence of a conductive object, such as a metallic implant, may compromise both the RF coil transmit and receive sensitivity homogeneity; especially in the periprosthetic areas. A further effect may be an increase of the local SAR which can affect the overall safety of the MRI exam. In this study, the outcomes of an electromagnetic cloaking strategy based on the application of a suitable coating to elongated conductive implants are shown. The coating restores the coil sensitivities and SAR distribution to those obtained without the implant presence.
