MRI image segmentation

I am doing 3D MRI visualization and I want to do bone segmentation , but there is a problem: the bone is white while other components in the image are white and I don't want it to be removed. So, I need to be able to differentiate to similar colors.

Please post a typical image. Hopefully hand drawing a successful segmentation so we know the goal.
