| Abstract: | Spatially localized one and two dimensional NMR spectroscopy has been demonstrated on a MRI system with a phantom sample of methyl methacrylete naphtyl ethylene copolymer. The conventional STEAM pulse sequence has been implemented for 2D NOESY experiment by incorporating increment time t 1.The results show high efficiency of suppression of the unwanted signal of H 2O by volume selection. The methods have potential application in vivo MRS study for obtaining valuable information. |
