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.
