A "Magnetom Vision" tomograph
was used to obtain in vivo magnetic resonance spectra of white brain matter
from a group of 16 healthy volunteers 19 to 60 years old. The paper presents
a software package for processing these spectra with minimal systematic
errors and estimation of confidence levels. For the group tested the mean
molar metabolite concentrations (mmol / L) of white brain matter were 10.70
+ 1.25 (N-acetyl-aspartate C(NAA)); 6.53 + 0.67 (phosphocreatine
C(PCr)); 1.67 + 0.35 (choline C(Cho)); 6.39 +
1.54 (myo-
inositol C(Ins)).
