Hello,
is there any recommendation from Freesurfer for MRI images used during recon-all? i.e., should we use a sagittal MRI, coronal or transversal? For instance, I have one subject with these 3 different orientations. I ran recon-all on the 3 of them and got the results for the reconstruction.
I was wondering how can we know which would be more accurate. I have a guess but not sure.
Thanks team.
Regards,
Daniel
Hi Daniel
these days you are better off getting a single 3D acquisition like MPRAGE rather than 3 orthogonal (thick slice) ones.

Hello,
do you have a specific sequence protocol we can use for doing tractography analysis (DW images) in Freesurfer? In the same way as you provide us with the MPRAGE sequence for T1 MRI. I would like to standardise the scans with the same protocol so we can use Freesurfer for the analysis. Thanks

Hi Daniel - Just make sure that spatial resolution is isotropic, and collect as many different directions as you have time for. Otherwise, we do not have strict requirements.
