  • Two-dimensional method for spectral editing of NMR signals produced by metabolites containing coupled spins
    Patent number: 4962357
    Abstract: An NMR method for acquiring the volume localized, in vivo proton spectra of spin-spin coupled metabolites employs a series of stimulated echo pulse sequences (90-TE/2-90-t.sub.1 -90-TE/2). The value of period t.sub.1 is different for each of the pulse sequences in the series, and the NMR signals produced by the series of pulse sequences are acquired and digitized to form a two-dimensional data array. A two-dimensional Fourier transformation is performed on this data array to produce an array of data that is employed to generate a contour plot.

  • Method for volume localized spectral editing of NMR signals produced by metabolites containing coupled spins
    Patent number: 4843321
    Abstract: An NMR method for acquiring the in vivo proton spectra of spin-spin coupled metabolites employs a pair of stimulated echo pulse sequences (90-TE/2-90-t.sub.1 -90-TE/2). The period TE/2 is set to optimize the signal components produced by the coupled spins of the metabolites. The value of period t.sub.1 is different for the two pulse sequences and the difference between the two resulting NMR echo signals provides the desired spectra.
