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
You can't get accurate surfaces from that, but the volumetric segmentation might be ok

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 Bruce
