Magnetic Resonance Spectroscopic Imaging (MRSI) is a signal-starved technique compared to conventional magnetic resonance imaging. At ultra-high fields, such as 7 Tesla the increased signal to noise permits the acquisition of improved spectra. Spatial localization performed the volume of interest is can be time consuming. We created a multi-region excitation pulse embedded within a B1-insensitive MRSI sequence and demonstrated its use in vivo to excite two distinct spectroscopic grids which are simultaneously acquired and disentangle using a low-resolution reference scan, thus accelerating the acquisition of MRSI data.
