I'm using 1.5T MPRAGEs. and the skull stripped T1 overall looks very bright. However the intensity for WM is between 90 and 120.

What is a typical example of when the intensity normalization process fails? Does the over-all image seem brighter? What is a good indicator of success or failure?
Thanks,
Tracy
