Figure 6

Numerically-calculated PRESS spectra of 2HG for various durations and bandwidths of 180° RF pulses and various subecho time sets. The envelope of the 180° pulse in (a) - (c) was the same as that used for in-vivo tests in the present study (see Fig. 1d of reference 10). The RF pulse for (d-e) had a different envelope (see Fig. 1b of reference 10). Spectra were broadened to Cr singlet width of 9 Hz. The singlet strength in (d) - (e) is smaller by ~10% compared to (a) - (c) due to the difference in ripple size in the refocusing profiles.
