Hi Pedro,
I tried to send you the image of my problem but the mailing list rejected my attachment, despite the file is only 769 k. How I can post an image in order to illustrate my problem?
Thanks,
Carolina

Hi Pedro,
Yes I have a case with heterotopia in the left hemisphere , I enclosed the image. I save the point in question (the gray matter region within white matter) in tkmedit and open it in tksurfer to know the thickness, for this I ask if FS takes into account the embedded region of the grey matter to measure the cortical thickness?
Thanks a lot,
Carolina

Carolina,
We have worked with several cases of MCD (including cortical dysplasia). We have published this paper: https://surfer.nmr.mgh.harvard.edu/pub/articles/jon_372_LR.pdf
It may help.
But in most cases of cortical dysplasia (not Gray matter heterotopia cases) you'll find a ticker cortex not a thinner one. But maybe you could post one image illustrate this problem.

Hello FSexperts
I have a MPRAGE image of cortical dysplasia, I have some regions of grey matter within the white matter, and I measured the cortical thickness in the projections of those regions and I expected to find a thinnercortex instead I found a cortical thickening. FS takes into account the embedded region of the grey matter to measure the cortical thickness?
Best regards,
Carolina
