EEG-fMRI at 9.4T: Safety assessment and effect on B0, B1 and fMRI scans in a phantom

{Simultaneous EEG-fMRI has been attracting significant attention from neuroscientists for the last 20 years. During these years, EEG-fMRI has been in use to investigate brain at different field strengths. However, so far, there has been no study examining the potential use of EEG during MRI at 9.4T. Therefore, in this study, we used a customized EEG and acquired data with RF heating, gradient heating, B0, B1, and fMRI using a phantom. The results revealed no critical increase in temperature in the EEG. However, there is an observable decrease in B1, which indicates the need for further research in this direction.}
