Dielectric pads have demonstrated to be a simple and yet efficient solution to mitigate locally RF transmission heterogeneities while using classic 7T MRI birdcage. Extensive research has not yet been carried on alternative candidate to water-based perovskites. The grail would be a long-lasting, comfortable, MR invisible, efficient, unalterable and high permittivity soft material. In this study, a novel material based on silicon carbide particles and addressing those requirements was successfully compared to perovskite pads from the literature in terms of B1+ homogeneity and image contrast through in vivo measurements.
