We report in vivo spectroscopic imaging of N-acetyl
aspartyl glutamate (NAAG) at 3T using PRESS-based
localization method. We present in vivo data from five
healthy volunteers. Repeatability, reproducibility
results and linear regression with white matter fraction
are also reported. Metabolites concentration maps are
presented to visualize the regional distribution.
