I think it should work for b0 images, but I would avoid using any frames
that have a gradient. Note that you will need about 10 images to compute
the fwhm using mri_fwhm (also make sure you use a mask)

External Email - Use Caution
Dear FreeSurfer developers,
Can "mri_fwhm" be used to estimate FWHM of b0 images (obtained from
diffusion-weighted echo-planar sequences) and is it possible to employ
for FWHM estimation from aligned diffusion-weighted images of the same
b-value but varying gradient wave vectors?
Thank you!
