Hi all,
I've noticed some signal dropout in my functional images and I think it may be throwing off my registration. Although the functional images that I'm working with have already been fieldmap-corrected, I am wondering if I need to/should include my fieldmap images in order to utilize BBR during registration.
Does specifying the fieldmap images for b0 unwarping influence registration with BBR? It seems like BBR accounts for areas of signal loss pretty well (masking those areas out of the registration, lessening their influence), so I want to make sure I'm using it correctly. Any input would be greatly appreciated!
Thanks,
Anika
