Abstract

It is demonstrated here that individual signal‐averaged NMR spectra can be compared statistically in a rigorous fashion. This is accomplished by considering the ensemble of single acquisitions, which are summed to produce spectra. Applications of this concept include assessment of the statistical significance of apparent metabolite variations in control preparations and quantitative comparison of signals obtained during the fast response period in functional MRI.

This paper deals with the problem of separating the spectra of signal and noise in ensembles where the signal can be considered as an invariant component and the noise as a stationary additive background. Several methods are discussed and compared on the basis of a statistical analysis of the first
