Hi!  
I have started a new project where I want to measure changes in distal part of mice femur. I want to know hot to evaluate bone morphometry in slicer 3D, however I have zero experience in this field. Is there any tutorial how to compute bone parameters(BV/TV, TbTh etc.) from scrach?  
Is it required to create a 3D model first or is the CT image alone enough? How to properly prepare a image for analysis?  
I found tutorial like this, but it doesn’t help me much (as I wrote I have no experience in this kind of analysis.)

I would be very grateful for any help!  
Thank you in advance

Iza
