(a) Numerically-calculated triple-refocusing spectra of GABA, Glu, and Cr are presented for Cr FWHM of 3 – 7 Hz. The concentration ratio GABA:Glu:Cr equals 1:10:5. (b) Spectra from an aqueous solution with GABA (3 mM), Glu (30 mM), and Cr (15 mM), obtained using the GABA-optimized triple refocusing, are presented for various Cr FWHM, similarly as in calculated spectra. Each of the calculated and phantom spectra was normalized to its Cr peak amplitude. A vertical line is drawn at 2.29 ppm.
