hi
I am working on severe TBI and most of them suffer from large hematoma and according to litterarture, the apearance on T1 changes accordind to the stage of the trauma, from 3days (early suba acute) to 14 days (late subacute) the T1 signal from hematoma is Hyperintense and after that it becomes hypointense. I want to know how freesurfer, especially the skull stripping or brain extraction step, deals with these two cases (i have both in my database). I want later to extract the cortical ribbon for tractography use.
Thanks
