Does anyone have any experience (good or bad) with registering a DTI image
to a T1 image? The images have different spatial resolutions, but are
oriented the same way.
I've been trying to do so, but the results are terrible. I've tried the
following methods so far:
1) Registered full head DTI (b=0) with full head T1 => poorly registered
because DTI image does not have enough contrast on the skull and skin, i.e.
those areas are relatively dark in the DTI relative to the brain. In the
T1, that's not the case.
2) Registered brain DTI (b=0) with brain T1 (brains were extracted using
BET with some post BET editing) => poorly registered but have no idea why
it should be
Any suggestions or insights would be much appreciated.
