Comparison of B₀ fieldmaps in mutant IDH1 glioma patient under four shimming conditions 2SH_box, 2SH_brain, 2SH_box + AC/DC_brain, and 2SH_brain + AC/DC_brain. Five representative slices are shown through the shimmed whole-brain slab with the tumor ROI contours. Standard deviation of B₀ distributions is given below for the entire slab and the tumor. Histograms of B₀ distribution over the entire brain slab are shown overlaid at the bottom for all the shimming conditions. FLAIR anatomical image is shown on the left most column.
