Dr Oz had a psychiatrist on his show recently by the name of Dr Daniel Amen. i was surprised because ive already been watching his presentations on public television for a couple of years before.

dr amen does PET scans and tries to use it for correctly diagnosing psych problems. which a few people here are right you cant DIRECTLY diagnose psych problems with a brain scan BUT you can possibly RULE OUT psych problems IF there shows to be an abnormality in the brain.

the other problems lie in the cost and the availability of this to everyone with psychiatric problems.
