Abstract

Abstract: This paper reports the experimental results of localized MRS using STEAM of MRI,in which the water signal in VOI is suppressed by presaturation radiation using shaped r.f pulses with two unequal widths in perpendicular phases.This water-suppression method is more effective than the dephasing method by gradient pulses.Among the threc kinds of common shaped pulses,the GAUSS shaped pulse is the best

Key words: Magnetic Resonance Imaging (MRI), Localized Magnetic Resonance Soectroscopy (MRS), Water-suppression, Shaped pulse
