Why not? Why prevent yourself from using a built-in function? Your post is not labeled as homework, which is usually the reason, so why not use it?
I was going to assume that you had 3 binary images, one for each segmentation that you want to do (background, gray matter, white matter) and that you could simply use nnz() on each binary image, but unfortunately you probably won't let yourself use nnz() either.
