Volumetrically Resolved TE-Averaged Spectroscopic Imaging

Kim D, Henry R

TE-averaged spectroscopy has been shown to isolate glutamate from glutamine at 3T. Extensions of this method to 2D spatial coverage have been previously implemented. In this abstract, we further extend the method to volumetric spatial coverage using spiral based readout gradients. The total exam time is within clinically acceptable range of 16:30 minutes. Echo time steps were carefully chosen to densely sample those area where the C4 proton had bigger amplitudes
