[Transverse relaxation time of metabolites by proton MRS: one of the parameters concerned with quantification].
We examined the transverse relaxation time of metabolites observed by proton MRS at 6 different points of TE(18, 30, 60, 90, 135, and 270ms). The double exponential curve was better fitted to the 6 points than the single exponential curve for calculating the T2 values of the three major metabolites. We considered that these metabolites would have a long T2 component and short T2 component, and the correct T2 value is difficult to obtain under the limitations of measurement time available in clinical applications.
