In this work, we compare the spectroscopy results and metabolite maps for different shimming routine. We use vendor default shimming technique and our own shimming technique. We tried to do shimming in different regions of brain (i.e. prefrontal cortex, occipital, and insula), also we tried to do multivoxel shimming. We compared the frequency shift maps between vendor’s implemented shim routine and our own shim algorithm. Also, we compared metabolite maps we got from different shimmed region after shimming using vendors and our own shimming routine.
