Plots show (a) the difference (mean ± SD) between FCs of the water resonance that are symmetrical about the main water peak, and (b) the percentage of pixels (mean ± SD) in each ROI with significant differences between symmetrical FCs. Note that while fewer pixels in the tumor rim have differences between symmetric components that are above the threshold, the mean difference at each frequency is much greater at the tumor rim than in other ROIs.
