A protocol with automated prescription has been developed for 3D spectroscopic imaging of the brain. Automatic placement of an oblique excitation slice and outer-volume suppression (OVS) bands instead of PRESS localization allowed for a fast prescription including full brain coverage. The use of novel dualband very-selective suppression (VSS) pulses shortened the length of the saturation pulse train and helped achieve sharper transition bands, compared to the existing nonlinear-phase single-band VSS pulses.
