Abstract
We review various applications of time-frequency and time-scale representations of signals in Magnetic Resonance Spectroscopy (MRS). First we give a brief survey of the mathematical tools, essentially the wavelet transform and the Gabor transform, both continuous and discrete. Then we turn to the applications and review the literature on signal correction and rephasing, solvent peak suppression, denoising, metabolite quantitation, etc. We conclude with some indications on available software.
