Abstract
High magnetic fields increase the sensitivity and dispersion in MR spectroscopy. Due to stronger susceptibility-induced effects, strategies for optimal shimming are of increasing importance at higher field. The problem of shim requirements which exceeded the active shim capabilities of our system by far was overcome by combined passive and active shimming. Optimal shimming enabled 1H MR spectroscopy in the primary visual cortex V1 of the macaque monkey brain.
