Hello!
This is probably a novice question, but here goes. We are using FreeSurfer to reconstruct the brains of a number of patients, some of whom have a bilateral T1 signal hyperintensity in globus pallidus due to manganese exposure. Problem is, this hyperintensity seems to confuse FreeSurfer and the subcortical segmentation goes a bit off -- parts of the pallidum is considered cerebral white instead (see attachment; globus pallidus is violet, putamen is pink). Is there any way this could be mitigated?
Thank you in advance :)
