In this work, we address the problem of B0 inhomogeneity in the human brain at 9.4T by using dynamic very high order B0 shimming. This enables multi-slice metabolite mapping in the human brain at this field strength. Furthermore, we investigate the advantage of low (2nd) versus very high (4th+) degree dynamic B0 shimming directly with respect to the quality of the metabolite maps.
