Metamaterials are artificial composites whose electromagnetic properties can achieve phenomena not observed in natural materials. The application of the metamaterials in MRI has been previously explored in several works. In this work, we explore the application of split-ring metamaterial slabs with zero and high permeability, which will reject and confine, respectively, the RF magnetic field at 1.5 Tesla. The experiments were performed in combination with a receive-only loop coil. SNR maps were calculated from a series of identical phantom measurements for both the =0 and the infinite slabs and compared with the situation where the slabs were removed.
