Single Echo Time Glutamate Editing at 3 Tesla

Yan Zhang¹, Stefano Marenco¹, Jun Shen¹

A method for measuring glutamate using a single echo time without employing any spectrally selective pulses at 3 Tesla was proposed. By adding an additional slice-selective refocusing pulse into the PRESS sequence and optimizing echo time and inter-pulse delays, glutamate editing can be achieved in a single shot without using spectrally selective pulses which are susceptible to B0 inhomogeneity.
