The aim of the current study is to optimize the
precision with which low SNR metabolites in short echo
time spectroscopic imaging data are quantified. We have
developed an algorithm that can be used to minimize the
glutamate/glutamine Cramer-Rao Lower Bound (CRLB) value
generated by LCModel on a voxel-wise basis.
