This investigation explores alterations of both cervical spinal cord and brain metabolite levels in normal appearing tissue in patients suffering from multiple sclerosis (MS). In the brain, a 2 dimensional J-resolved spectroscopy sequence and 2D prior-knowledge fitting is used and the metabolite cycling technique is applied to the cervical spinal cord at 3T. Relapsing-remitting MS (RRMS) and secondary progressive MS (SPMS) patients are included and alterations between brain and spinal cord metabolites are addressed.
