Brain scan

Ever had a brain scan done that shows your autistic brain working differently (than other brains)? 

It would be useful to have an entry on autism.org.uk but is there one? Seems there isn't yet.

I'd be curious to find out in which cases the scan is radically different, for example.

And it probably varies for each individual, but along with some regularities as well.

(I don't mean so much for diagnosis, though.)
