Subject: [Freesurfer] High resolution fMRI and resolution of anatomical
scans
Hi,
We are planning to collect high resolution functional MRI for a group of
subjects with voxel size smaller than 1 mm. For these subjects, we already
have reconstructed anatomical scans with 1 mm voxel size
You do not need another one unless you think that the brain has changed
in some way between when you collected the anat and the func. Also, if
you are going to acquire a partial field of view (ie, only part of the
brain), make sure you get a full brain acq of something to help in
registration
We always collect a low resolution whole brain mprage structural scan
before the functional scans to help us position our slices. Can I use
that?

yes
