We have developed and implemented a fast spectroscopic imaging acquisition for selective homonuclear polarization transfer sequence for the detection of GABA at 7T. With the high SNR available at 7T, whole slice studies of 1.65cc nominal resolution are achievable with acquisition durations (5 to 10min) conventionally used in single voxel studies. As this editing is performed with longitudinal magnetization, this method is single shot and is flexible for evaluation of multiple coupled spins.
