In this work a method for absolute quantification of proton MRS is presented. The method are base on using the internal water as an reference an Quantitative MRI for absolute quantification of the internal water. Since measurements of the internal water signal is done automatically before any proton MRS measurement and the the qMRI volume only have to cover the voxel the method becomes very user independent
