Re: [Freesurfer] Recon-all with lower resolution T2 / Proton Density reconstructions and higher res T1

Hi Bruce,

1) I was also concerned 3mm may be too thick but I will try a few subjects to see how it goes.

2) Hi Eugenio I wanted to see if you can give a bit of insight into the hippocampal issue.

3) Bruce, sorry for the confusion. I was referring to sqrt(T1w*B1 x T2w*B1) ~ B1 bias field estimate not the T1/T2 myelin mapping.

Do you see any forseeable issues of correcting the T1w and T2w image with the B1 estimate prior to running myelin mapping (T1/T2)? Essentially if we remove B1 already then there should not be any additional B1 cancellation when dividing the images.

Do you see any issue with using the same B1 bias field to correct resting state data after motion correction is performed?

Thanks, Ajay
