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?

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
I'd collect highres T1w as well and then refine the 1mm surfaces using that.

Hi,

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. The
question is, do we need to re-collect *anatomical* scans for these subjects
