Abstract
Accurate values of metabolite relaxation times are necessary for absolute quantification in magnetic resonance spectroscopy (MRS) and for comparing spectroscopic data obtained at different field strengths. Metabolite T1 relaxation times have been determined for different regions of the human brain in several studies at 1.5 T, but data on T1 values at 3.0 T are available only for occipital grey matter (GM) and white matter (WM). The objective of this study was to compare T1 relaxation times of brain metabolites in six different brain regions in normal adults at 1.5 T and 3 T.
