Dear SPMusers,
after routine segmentation in spm5 for vbm we see (in some datasets) relatively
strong gradients in intensity within the image, especially midcingulate portions
and ACC become bright (see attached examples).
It seems there is a tendency to get this result in elderly patients with larger ventricles.
With regard to the position of the cortex band, the results are satisfying.
To my understanding, the translation parts of affine transformations do not have an effect
on modulation (for example when the stretched out cingulate cortex is shifted to its normal(ised) position).
We just wonder if these datasets need to be taken out.
thanks a lot for any hints,
Philipp
