Relaxation
times are often an assumed value in spectroscopy studies, despite their
potential diagnostic value and usefulness in quantifying metabolite
concentrations. The purpose of this
study was to measure the transverse (T2) relaxation times of the major brain
metabolites (NAA, Crt, and Chot) in left and right basal ganglia of veterans
with Gulf War Illness (GWI) and age-matched veteran controls to determine if
the T2 values differ between ill veterans and controls or among the three syndrome variants of GWI.
