Effects of high dielectric material (HDM), that has a size larger than the coil element of a parallel receive array, are theoretically studied at 3T. The results suggest that the gain from receive sensitivity of the array brought by the HDM overcomes the enhanced g-factor, which can promise to improve signal-to-noise ratio even when the HDM has a size which is larger than the coil element of a parallel receive array.
