Non-human-primates are a valuable model for investigating the structure and function of the brain. The high-dielectric pads have been shown to increase B1 sensitivity and enhance image SNR and contrast locally in the human brain at high and ultra-high field. In this study, our pilot experiment results suggest that high-dielectric pads can effectively enhance macaque whole brain imaging at 7T, and in the meantime, do not increase the receive array element coupling, nor have any deterioration over the B0 homogeneity within the monkey brain.
