In this study we performed invivo T2 measurement of metabolites like N-acetylaspartate, Creatine, Choline and water in glioma patients for comparison with normal brain using single voxel point resolved spectroscopy at multiple echo times at 3T. We calculated T2 using monoexponential nonlinear fitting of metabolite signal estimates obtained from LCModel.
