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.
