 Abstract: Single voxel spectroscopy benefits from the use of multi-channel coils. Several methods have been proposed in order to increase the signal to noise ratio of the combined spectrum. In particular, three methods (Brown’s method, singular value decomposition method and generalized least square) were studied to access their performance and robustness. For this purpose, simulated data were created mimicking spectrum under different decoupling conditions, in vivo data were also used. The results demonstrated that the methods produces combined spectra with similar values of SNR. However, their robustness varies in a high degree.
