The fundamental limit for NMR imaging is set by an intrinsic signal-to-noise ratio (SNR) for a particular combination of rf antenna and imaging subjects. The intrinsic SNR is the signal from a small volume of material in the sample competing with electrical noise from thermally generated, random noi
## Abstract Moving average can be used to improve the signalβtoβnoise ratio of NMR kinetic studies. The method was tested on simulated spectra with timeβdependent intensities or peak positions. It was then applied to a series of __in vivo__ spectra, showing the pharmacological effect of heptaminol
