Spinal cord functional magnetic resonance imaging studies have typically used task-based paradigms to elicit activation, but a recent resting state study at 7 Tesla demonstrated the existence of resting state networks in the human spinal cord. In this abstract we translate the acquisition, preprocessing, and analysis methods developed at 7 Tesla down to 3 Tesla. Our results suggest that with a longer run length these spinal cord networks may similarly be detected at 3 Tesla, and therefore may have immediate and widespread clinical applicability for studying diseases of the central nervous system.
