Would the fa image itself be useful for that purpose? That's essentially a vectorless representation of diffusion

What I meant by "isotropic" diffusion image (iDWI) was not a spatially
isotropic image, but an image that shows diffusion but does not contain any
information about the direction of the gradients applied. I was hoping to
threshold this image to use to skullstrip the rest of the DWI data because
non-brain tissue is very low intensity in this type of image. I am doing
work in monkeys and BET doesn't do a very good job. Any suggestions would be
very much appreciated.
