Sodium MRI/MRS benefits of improved SNR obtainable at high fields (3-12 T). Surface TEM resonators are especially designed for high-field applications. In recent works a novel double-tuned (DT) surface TEM resonator, made by three microstrip elements and suitable for sodium and proton MRI at 4T was described.
