       In this paper the effect of coupling metamaterial cells with a coil to achieve Magnetic Resonance Imaging (MRI) is investigated. Both an array and a single spiral-shaped metamaterial are associated to the coil antenna. The goal is to increase the sensitivity of the whole system and to improve the homogeneity of the RF magnetic field pattern. The spiral-shaped metamaterial associated to the antenna gave very promising results in simulation. We are currently fabricating a sample to confirm the results of the simulations.
