Hi all,
I was having some problems bet extracting some of my
structural scans, I was getting a lot of left over neck that was screwing up
the alignment. I noticed the current version of bet has a new option flag (to
me at least), which focuses on cleaning up the neck.
The option is –B . When using this flag the processing
takes considerably longer, something along the lines of 10-15 mins per scan.
However, not only did it resolve the issue, but the resulting image looks
cleaner and more precise than I would expect from a normal bet. I’ve
attached a comparison image so you can see the effect.
I did similar comparisons running this flag with functional
data and it also shows improvements. At the moment I’m re-processing my
data files in this way before running my analysis.
I thought I’d mention this in case it might be a
useful option for other people to use, but also in case anyone knows any reason
why it might be problematic. I’d be keen to know if anyone knows of any
reason why I shouldn’t use it? I notice the overall intensity seems
slightly lower when this flag has been used, is this likely to be a problem?
Cheers,
Chris Racey
