Question-- do the reports need to visualize the inhomogeneity outside of the brain or do you think we should just mask it so that users don't get alarmed by the amount of out-of-brain field inhomogeneity?
This question is THE QUESTION. On the one hand, I do agree it is alarming (especially to the non-familiar eye). On the other hand, I think it is nice to compare how different methods regularize outside the brain differently. For instance, the traditional FUGUE correction (the infamous epiunwarp.fsl script) extrapolates (constant) the values at brain edges along the PE axis. That produces this kind of "rays":
