We apply CEST to healthy cervical spinal cord at 7T and compare the results with our previous studies at 3T. We hypothesize that development of spinal cord CEST could reveal the health of the spinal cord and its relationship to disease earlier than conventional methods. Results include calculation of the amide proton asymmetry effect by integrating the area between a Lorentzian fit and the acquired CEST spectra. APT asymmetry maps at 7T reveal white/gray matter delineation but the mean values of 5 healthy controls were not significant.
