ABSTRACT
Glutamate (Glu) is a major primary excitatory neurotransmitter of the central nervous system Recently a TE-averaged MRS is proposed to simplify the quantification of the Glu peak using successive shift echo time in scan parameter at the expense of prolonged scan time. Here we propose to map the 2D Glu distribution in the brain using radial Proton Echo Planar Spectroscopic Imaging (rPEPSI). The radial readout trajectory is superior in possible data sharing property which makes it more flexible in combination with TE-averaged technique.
