Figure 2.

Representative transversal slices of all quantified 3D metabolite maps from the patient with low-grade glioma (astrocytoma WHO 2; cf. Figures 1A,B), shown as intensities in arbitrary units. Note the different scales for the individual metabolites, and that all maps are subject to the coil sensitivity profile. For visual guidance, the metabolite maps are masked to show only brain parenchyma as displayed on the 3T T2-weighted FLAIR images (co-registered to the MPRAGE images obtained at 7T).
