In the past few years, graphene has been widely developed and considered as evolutional nano-materials, which could potentially advance the scientific researches in physics, electronics, optics and biomedical applications due to its remarkable physical characteristics. In this study, we aimed to develop surface RF coils coated with graphene materials for 3T MRI use and perform a quantitative comparison in signal-to-noise ratio (SNR) of graphene and conventional copper RF coils. Our preliminary results show a consistent improvement of SNR of approximately 1.38 folds in average, which could be potentially useful to help gain higher spatial resolution or temporal resolution than conventional copper coil in future studies.
