In this study we use 1H MR spectroscopy to investigate
if a conventional short echo STEAM sequence can be used
to measure glutathione in the brains of 14 healthy
controls at 3T. The STEAM results are compared to that
of MEGA-PRESS spectral editing. There is a strong albeit
non-significant correlation between glutathione measured
by MEGA-PRESS and STEAM. Additionally, glutathione
measured in the STEAM sequence shows a low intra- and
inter-subject variability of 5.4% and 10.8% respectively
compared to the inter-subject variability of around 17%
using MEGA-PRESS. Further work is now needed to validate
these initial results.
