Evaluation of new MRI invisible silicon carbide based dielectric pads for 7T MRI

Dielectric pads have demonstrated to be a simple and efficient solution to mitigate local RF transmission heterogeneities while using classic single or dual transmission channels 7T MRI. Extensive research has not yet been carried out on alternative candidate to water-based perovskites. The grail would be a MR invisible, comfortable, efficient, stablehigh permittivity soft material. We present here a novel mixture tested to satisfy these requirements. It is compared in simulations to previously studied solutions in terms of permittivity conductivity, B1+ homogeneity and safety. Then, the results are confirmed through preliminary in vivo evaluation.
