A 16-channel tongue coil was recently developed with the purpose of improving tongue SNR compared to existing coils. We examined the potential use of parallel imaging with this coil, including an analysis of g-factor for mid-sagittal 2DFT and 2DPR sampling, with a range of acceleration factors. We show that 4x acceleration can be achieved with 2DFT and 5x acceleration can be achieved with 2DPR, with g-factor less than 4.0 in all tissues of interest in the upper airway.
