Is it possible to scan a mouse or rat using MRI to define 3D CSF space geometry (make a 3D model of it for numerical modeling purposes). I am not sure if even at the highest MR imaging resolutions (17 or 21T scanners) it would be possible.
What is your resolution need? T2 imaging could trivially give you the CSF spaces, depending on what you really need. I would talk to your small animal imaging core since it should be straightforward for them.
Thanks for your thoughts on this Yueh! I think it is not possible with my animal imaging core because we do not have a magnet with high enough resolution.
