Comparison of MEGA-PRESS edited spectra at 4 and 7 T. Top: editing for Asc at 4 T (from our previous study (7), VOI = 3 × 3 × 3 cm3, TE = 112 ms, TR = 4.5 s, NT = 512, 40 ms editing pulses at 4.13 ppm). Bottom: editing for Asc at 7 T (this study, VOI = 2 × 2 × 2 cm3, TE = 112 ms, ms, TR = 5 s, NT = 512, 40 ms editing pulses at 4.01 ppm). Both spectra were measured from the human brain occipital lobe using quadrature half-volume RF coils and post processed with a Gaussian filter, σ = 0.1 s.
