MRS results from a cylindrical phantom containing 20% natural abundance glucose solution. Spectra were acquired with 8 averages, and the voltage of the WALTZ-16 scheme, consisting of 180° block pulses with a duration of 1.5 ms, was increased from 0 to 180 V in steps of 10 V. Decoupling starts to become effective at ca. 70–80 V and reaches optimum performance at 100 V decoupling voltage and above.
