Automated methods to segment dural venous sinuses

, ,
1

I’m particularly interested in superior sagittal sinus, which, according to Tong, Hocke, & Frederick (2019), is a good ROI for correlation analysis with rapidtide.

I came across this old Freesurfer mailing list post from 2012, in which Freesurfer devs are not aware of any segmentation methods for dural sinuses. I’m hoping, though, that there’s been some progress on this, although I haven’t found any information about it in Freesurfer’s documentation or online.

Fressurfer version 8.0 seems to have a new function that does this: mri_vsinus_seg
https://surfer.nmr.mgh.harvard.edu/ftp/dist/freesurfer/dev_binaries/centos7_x86_64/mri_vsinus_seg

# Sample call
# Segment Venous Sinus using mri_vsinus_seg from FreeSurfer V8
 	if [ ! -f ${outdir}/vsinus.mgz ]; then
    	mri_vsinus_seg \
      		--i ${SUBJECTS_DIR}/sub-${subjID}_ses-01/mri/nu.mgz \
      		--o ${outdir}/vsinus.mgz \
      		--outdir ${outdir} \
      		--ctxseg ${SUBJECTS_DIR}/sub-${subjID}_ses-01/mri/aparc+aseg.mgz \
      		--threads 8
    fi
      
    # Convert output to nifti 
    if [ ! -f ${outdir}/vsinus.nii.gz ]; then
    	mri_convert ${outdir}/vsinus.mgz ${outdir}/vsinus.nii.gz
    fi

It outputs a mask with the following labels

  6111  Left-Transverse-Sinus           
  6112  Right-Transverse-Sinus       
  6115  Straight-Sinus                
  6116  Superior-Sinus-P               
  6117  Superior-Sinus-D
