Abstract
Brain glutamate and glutamine were detected in healthy human volunteers in spectroscopic images with a nominal voxel size of 2.25 cm^3^ at an echo time of 15 ms. Due to the increased frequency separation and simplification of Jβcoupling patterns, the separate detection of brain glutamate and glutamine at short echo times was possible. Creatine, choline, and Nβacetylaspartate with other Nβacetylated compounds were also detected. The ratios of the metabolite resonance intensities were in agreement with previously published values.

## Abstract The method of single quantum ^13^C editing is analyzed and implemented with water suppressed __J__βrefocused coherence transfer spectroscopy. Analysis of the ^13^C inversion pulse demonstrates that it is optimally placed into the second echo of the __J__βrefocused sequence. We have used
## Abstract For spectroscopic imaging studies of the mouse brain, it is critical to obtain optimal __B__~0~ homogeneity over a large region of interest (ROI). In this paper, a fully automated shimming method for mouse brain at 9.4 T, based on __B__~0~ mapping, is described. __B__~0~ maps were obtai
