Acquiring high-quality functional MRI data of the spinal cord is challenging due to large susceptibility artifacts and high physiological noise, causing signal dropout and distorsions, particularly in the cervical region. This study demonstrated the beneficial effect of using non-protonated perfluorocarbon liquid-filled SatPads^TM during fMRI acquisition. Indeed, results show an increase of 31.51% for the global signal and 36.59% for the temporal signal-to-noise ratio for resting-state fMRI data acquired in the cervical spinal cord.
