Hi FSLers,
We acquired separate b0s to go with our DTI (because we use Philips
scanner and it doesn't allow us to acquire multiple b0s in the 4D DTI
scan). However, we found our separately acquired b0 images have higher
intensities (about 1/3 higher )than the b0 in the 4D DTI image, even
though we used the same TR/TE etc. It might be a scaling thing I think.
I was then wondering what/how this different intensity of the separate
b0 would impact on the computations. What we intend to do is: a) merge
separately acquired b0s into the 4D image and then b) eddy correction
etc c) usual dtifit ...
Hopefully you can shed some insight to this question/problem.
Many thanks and regards,
Wei Wen
