Dear Shaquanda,
it seems like you're not using the appropriate template to normalize
your images...
The cost function for the normalisation procedure is based on the sum of
square of differences between voxel *intensities*. If the images
contrast is different, you cannot directly compare their intensity.
The template you've selected is clearly the T1 weighted MRI, while your
image looks like a T2. You should thus retry with the T2 template.
And, also make sure that your image is +/- aligned with the template
before normalising. If not, adjust your image orientation manually
through the display tool and 'reorient images' button.
Best,
Chris
