Functional MRI of the spinal cord is challenging due to its small size and deep anatomical location. Increasing field strength enhances BOLD signal and improves SNR, but B0 distortions produced by the lungs and vertebral column are amplified, presenting additional challenges in protocol optimization. Barry et al. have successfully performed resting-state fMRI at 7T; here, we present observations of robust, well-localized motor task activation in the human cervical spinal cord at 7T. We assessed single-shot and multi-shot EPI at two different resolutions. Multi-shot EPI achieved finer resolution and less spatial distortion in this preliminary 7T spinal cord task fMRI study.
