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 (Browns
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.
