Dear Experts,
I've been collecting hi-res hippocampal scans with a 32 ch coil on a 3T Siemens Trio to manually segment hippocampal subfields. However, I wonder whether the protocol is appropriate for use with the new Freesurfer subfield segmentation tool.
Specifically, our hi-res scan does not capture the entire brain, rather it acquires slices perpendicular to the long axis just for the length of the long axis axis. Can this scan be used for the new subfield auto-segmentation? Or does it require a whole-brain acquisition?
We do acquire a 1 mm isotropic whole brain MPRage, but...
Thanks for any info, Joshua
