Fig.5.
J-modulated spectra with starting echo times (TEs) of (a) 35 ms and (b) 77 ms. Unlike the spectrum with TE = 35 ms, which was multiplied by a 110 degree phase factor, an overall phase of 150 degrees was applied to the spectrum with a starting TE of 77 ms, in order to turn up the phases of glutamate (Glu) and glutamine (Gln) peaks. These two spectra were used to estimate the Gln T2. The simulated sub-spectra in (b) show partial overlap between Glu and Gln around 2.35 ppm.
