Hello Surfers, I have a number of subjects that are displaying a large number of small holes in the superior region of their white matter. I believe the medical term for them is virchow-robin spaces. We would like to try to quantify the volume that these holes occupy. Is there any way to break down the Right-Cerebral-White-Matter and Left-Cerebral-White-Matter segmentation labels in aseg.mgz into finer regions so that we can quantify the volume of these holes? Or would it simply be easier to go through the volumes and manually label the holes as a label that is not being used?

Thank you, Jeff Sadino
