@aalaa12341,

A quick an easy way to do this is to:

1. Segment the tissue or structure of the brain that you are interested in using the **Segment Editor**  

2. Calculate a volume of the tissue or structure by using the **Segment Statistics** module  

Also, I used the MRHead sample dataset available with 3D Slicer for practice!
