Weighted Combination of Multichannel H-MRS Data: Comparison of SNR- and SVD-based Methods by simulated, in vitro and in vivo data

Fig. 2: In vivo spectra reconstructed from the 12channel data set (NAS = 256) by using nonweighted channel combination (blue), WLCSNR (red) and WLCSVD (black). As quantified by the amplitude of the NAA peak at 2.01 ppm signal gains of 12% and 17% were achieved using the WLCSNR and WLCSVD, respectively, relative to SLC.
