Re: [Freesurfer] intensity normalization failure

[Tracy Wang]

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.

Hi


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
