PET refacing
Hi
Just wondering what the difference is between the "FBP" and "FBB" image types. We have both Florbetapir and Florbetaben scans. Both options for `mri_reface ... -imType` are logged as "Target image type: Amyloid PET (F18)". Do they use the same atlas behind the scenes?
Thanks
Paul

Paul,
At this time, FBB and FBP are doing the same thing behind the
scenes. PIB and NAV use one template based on PIB, and the other
F18 tracers use another template based on FBP. It's possible that
some future version may need to differentiate them, but currently
that pair are treated the same internally.
