Hello everyone !  
I’m looking to segment aortic, and especially mesenteric vessels from post-op CT scans after colectomy.  
My senior researcher wants me to do something like this :

On a CT scan with similar constrats between portal and arteric vessels : how would you do it ?  
For example, like this ![image](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/2/b/2b42f218fff8f7da059cbd4ab15487e2b591dbab.jpeg)

In fact, I need more the arteric vessels than the portal ones.

I don’t know if i should choose local treshold or manual painting with maybe grow from seeds ?  
How would you do it ?  
Thanks a lot  
Thomas
