Moving average improves the signal-to-noise ratio of kinetic studies in magnetic resonance spectroscopy.

Moving average can be used to improve the signal-to-noise ratio of NMR kinetic studies. The method was tested on simulated spectra with time-dependent intensities or peak positions. It was then applied to a series of in vivo spectra, showing the pharmacological effect of heptaminol on the intracellular pH of perfused hearts.
