Number of pixels after segmentation

Can I read the number of pixels / voxels somewhere after segmentation? Not only their volume, I mean their quantity. So far, I have been able to obtain results from the Segment Statistic module.

What quantity would you be interested in? Number of voxels? Bounding box size in mm or voxels? Segment Statistics module should provide you all these.

Thank you very much for your answer! I have one more question, where
can I find information on the size of the voxels?

size of the voxel = Image spacing in X * Image spacing in Y * Image spacing in Z direction

You can find image spacing information in the Volumes module

Or from the Segment Statistics module, you can calculate the size in mm^3 as follows

Volume [mm^3] / Number of voxels
