Re: [Freesurfer] ASL perfusion maps

We don't have an MC program. You can try running FSL's FLIRT or AFNI's 3dvolreg. As for analysis, you should be able run

mri_concat --paired-diff --mean inputaslvolume outputvolume

I've never actually tried it like this, but it should work.

Hi all

I have collected some raw Arterial Spin Labeling (ASL) data. I would like to use freesurfer to create perfusion maps of this data. Is it possible to take the raw data, motion correct it, perform a pairwise subtraction, and then average all the subtractions to create a mean perfusion map? Please let me know if you have ideas on how to do this sort of thing.

Thanks Abi
