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.
