A new algorithm to improve eddy current correction and
residual water removal was proposed and tested on in
vivo single-voxel MRS data acquired from 141 healthy
subjects. From the water reference scan the metabolite
signal was subtracted to reveal water sidebands.
Together with HSVD fit this method improves spectral
baseline and allows accurate quantification of single
voxel MRS.
