Vessel Segmentation for carotid artery with stenosis

Hi all,

I am pretty new to 3D slicer, and would very much appreciate your help

I am trying to segment and export a .stl file of the carotid artery with stenosis based on CT images with contrast.
Since I am planning on handling 100+ patients’ data, I am trying my best to automate the process as much as possible ( and minimize user variability).

Granted, I have tried flood-filling / grow from seeds, and scissor-ing from the 3D view (threshold 235-600 HU). For all 3 methods, I need to manually erase/paint the lumen for each image due to the plaque and stenosis. Due to the low resolution when zoomed-in and the small cross-sectional area at the region of stenosis, this erase/paint process always leads to high variability.

Is there a more sophisticated way to achieve this? Or is there a guideline that I could follow?

Any guidance or information would be deeply appreciated.

Thank you!
