One little image slice isn't enough to determine much if anything, especially when there's about 60 sheets of about 100 images on each sheet. Believe me, I've had both an MRI and CT scan before (November 2004). The weight of just the MRI scan results is about 10 pounds of paper.
The guy who's seen 10,000 of them has a different opinion on the matter. Why do you think yours is more correct than his?
