## Abstract In this work, a new double quantum filter for glutathione (GSH) editing is introduced, combined with the pointβresolved spectroscopy localization sequence (PRESS), and demonstrated in vivo. Compared to the conventional double quantum coherence filter, the new filter has two major advant

Abstract
A method is described to selectively measure lactate in vivo using proton zero quantum coherence techniques. The signal from lipids is eliminated. A surface coil and additionally slice selective localization are used. The resulting spectra demonstrate the good performance of the method. Β© 1991 Academic Press, Inc.

A volume-localized, two-dimensional NMR method which unambiguously measures lactate protons in the presence of interfering lipid resonances is presented. This technique employs the stimulated echo method for spatial selection and was used to observe lactic acid levels in a subcutaneously implanted R
## Abstract A proton MR spectral editing technique employing a spatially localized, doubleβquantum filter (DQF) was used to measure Ξ³βaminobutyric acid (GABA) in the human brain at 1.5 T. The doubleβquantum method provided robust, singleβshot suppression of uncoupled resonances from choline, creati
