Magnetic susceptibility differences between grey matter (GM) and white matter (WM) can potentially affect lineshapes and chemical shifts in single voxel spectroscopy. Hitherto, analytical techniques such as LCModel assumed a single lineshape per voxel. Separated GM and WM signals using multi-echo GRE image sequence in combination with literature values for the metabolite distribution between GM and WM enable to construct a realistic basis set for LCModel. With this information we can test how magnetic susceptibility induced lineshape modification affects metabolic quantification, which uses spectral prior knowledge.
