Dear FSL experts:
I have scanned DTI data for about 40 subjects, each with 32 directions of b=800 and 1 b0 image in 3T Philips,
But in some subjects, seems to have a signal drop-out for some of the axial slices in a few of the gradient directions,
see (A) in the attached figure. And almost in all the subjects, there are artifacts (zebra lines) in many graident directions and
these zebra lines are mostly in cerebellum, see (B) in the attached figure.
Is there anyone who has any experience in this issue? Any comment /suggestion how to avoid or correct these artifacts when processing these DTI data will welcome. Thanks ahead
All the best
Shugao
