Dear all,

 

I need to mark the cortical extent of a lesion (intersection of the lesion and pial surface, where "lesion" represent a epilepsy related resection). After the pial labeling of the resection, I need to register the labeled surface to the fsaverage.

I completed recon-all routine on the postop T1, and went nicely, corrected pial surface in a few places.

Question: what is the best way to mark the pial extent of a resection? Is there a way to accurately register the lesioned pia to the fsaverage, potentially by masking the resection ROI?

Thank you for your insight,

 

Octavian.
