In diffusion weighted spectroscopy (DWS), the behaviour of intra cellular metabolites can potentially give information on compartmentation, in contrast to water for which measurements are not specific for any compartment. In this work, we measure for the first time in humans the different diffusive properties of N-Acetyl aspartate (NAA) and N-Acetylaspartylglutamate (NAAG) by applying DWS at a field strength of 7T, where there is sufficient spectral separation to perform this measurement
