The combination of constant-time point-resolved spectroscopy (CT-PRESS) with optimized broad bandwidth refocusing pulses (S-BURBOP) improved the signal detection of homonuclear coupled spins by reducing the chemical-shift displacement error. The signals of Lactate, Glutamate, and Glutamine were significantly increased in evaluations in a phantom and in healthy volunteers.
