Three combined spectra, one for each scan, of the second normal volunteer computed using the GLS method. Voxel size = 3 × 3 × 3 cm3, TE1 = 37 ms, TE2 = 63 ms, spectral width = 4000 Hz, number of samples = 2048, number of acquisitions = 128. For the first and second scans, no OVS was applied and TR = 2.5 s. For the third scan, OVS with six slabs were added to the pulse sequence and TR = 4.3 s.
