Hi Hengameh

You can try, but 3mm may be too thick for accurate surface models. Once you have too many voxels that contain both sides of a sulcus it is difficult to recover accurate surfaces. Note that our inputs don’t have to be mprage, but 3D acquisitions are highly recommended

Cheers

Hello Freesurfer developers,
 
I have T1 weighted MRI images which are not MPRAGE. They are 2 dimensional sagittal or axial images with 3mm thickness (1.5 Tesla).
Can I analyze these images by FreeSurfer?
If yes, what tips should I consider?
 
Thank you in advance,
Best regards,

Hengameh
