Clinical magnetic resonance spectroscopy is rarely applied in the spinal cord due to technical challenges leading to a low spectral quality and thus to a limited number of reliable detectable metabolites. In order to extend the metabolite profile an increase of the spectral quality is necessary, which could be achieved by both: averaging a high number of FIDs and by using a dedicated neck coil. Besides N-acetyl aspartate, creatine, choline and myo-inositol a reliable detection of scyllo-inositol and glutamine/glutamate was possible. Increased myo-inositol/creatine and scyllo-inositol/creatine ratios compared to brain estimates can be observed in the spinal cord.
