LCModel fitting of a short TE spectrum, with TE = 35 ms, voxel size = 8 mL, average number = 128. (a): original data; (b): in vivo data with the noise level increased by 55%. An increase in estimated glutamate (Glu) concentration from the noise-increased data is accompanied by a decrease in the estimated baseline intensity near 2.35 ppm. The arrows show the change in baseline intensity near 2.35 ppm.
