Pulling a skull from MR

Are there any tips for pulling a skull from MRI images? In this sequence the skull is very comparable in the number as other brain matter/soft tissue.

I woild recommend the HDBrainExtraction extension for skull stripping. See some more details in this recent discussion:

I use the HD brain extraction to get a brain segmentation, but this can be used to KEEP only the skull??
Thank you!

Yes, sure, you can blank out the brain region by a few clicks.

  • Create Brain segmentation output in HD Brain Extraction Tool module
  • Go to Segment Editor module
  • Click Mask volume effect, Fill inside, and Apply

I tried this option, but it doesn’t work the best for getting only the skull. When thresholding it merges right with how it was masked. ANy other options to get a skull only, no soft tissue? Thank you for your help!
