We have the same problem using the same coil (GE 750; mainly occipital
pole), so any suggestions for how to correct this would be very helpful.
Thanks!

Hello Freesurfer experts,
We have T1 data from a 3T GE 32-channel head coil that exhibits areas
of hyperintense white matter. Specifically there are areas of the
wm.mgz on the periphery with values ranging from 117-121, which lead
to overextending/overestimation of the wm.mgz.
1) Can anyone suggest specific processing options or flags to help
correct for peripheral hyperintense white matter?
2) Can anyone suggest methods of correcting for local overestimation
of white matter on the periphery?
Your help is greatly appreciated!
Doug
