The distribution of magnetic fields can be tailored using high dielectric materials. Here, we introduce a new material with high and tunable dielectric constant, and also low background MRI signal. The material is based upon metal titanates, which can be made into a geometrically-formable slurry by combining with deionized water. Results obtained at 7 Tesla show a significant increase in image intensity in areas such as the temporal lobe and base of the brain.
