spectroscopy of Glutamate, Glutamine, N-acetyl aspartyl
glutamate (NAAG) and other metabolites in human brain
using PRESS at 3T. With test- retest experiment, we
present the ability to reliably detect and quantify
these technically challenging metabolites. With the
segmentation of gray matter and white matter, we also
demonstrate variation of the metabolites in different
brain regions.
