9. PRESS ROI Superimposed on S19.6 Image: Ratio of the Cho/NAA

10. Mathematical Model: Gaussian function Full width at half maximum

11. CholineCholine CreatineCreatine NAANAA Spectrum from 3 Gaussian functions

14. Voxel Wise Distribution

16. Conclusion : Analytical expression to compute the area which represents the concentration of the metabolites. Next Step: To compare with our ratios with Functool ratios Suggestions are welcome
