The linear prediction z-transform method (LPZAR) was applied to estimate 31P NMR spectra of perfused rat hearts. The spectra obtained by the LPZAR method showed sharper peaks with less noise for phosphate concentrations than those obtained by conventional fast Fourier transform. The LPZAR method provided a better estimation of intracellular phosphate concentrations in short acquisition time experiments in which condition Fourier transform spectra are not suitable for the quantification due to the poor resolution of FFT spectra. Utilizing the LPZAR method, rapid changes in phosphoric metabolites of the heart can be monitored during ischemia followed by reperfusion.
