摘要：

A method is introduced for obtaining proton spectra in vivo with all the advantages of a full water signal, The method, based on F-1 oversampled J-resolved spectroscopy, makes it possible to separate metabolite signals from unwanted baseline artifacts. The dominant water resonance is used as a 2D reference signal for the phase-sensitive reconstruction of the 2D J-resolved metabolite spectra, The powerful specificity of this method is demonstrated with model compound spectra, phantoms, and in vivo examples.
