An electrical lead, for implantation in an animal, is compatible with an MRI scanner. The electrical lead has a first plurality of coiled insulated wires forming an outer layer of conductors that has a first inductance and a first capacitance, which act as a first parallel resonator tuned to a Larmor frequency of tissue in the animal. The lead may have a second plurality of coiled insulated wires forming an inner layer of conductors within the outer layer of conductors. The second plurality of coiled insulated wires has a second inductance and a second capacitance that act as a second parallel resonator tuned to the Larmor frequency. Those parallel resonators mitigate signals at the Larmor frequency from traveling along the respective coil. An electrically conductive layer extends around the inner and/or outer layer of conductors, and a layer of a biologically compatible material forms the electrical lead's exterior surface.
