A snapshot of the brain may be able to reveal if someone has autism.

British scientists say they have developed a rapid test that would take only about 15 minutes and could help doctors diagnose the disorder cheaply and more accurately.

Experts at King's College London tested the scan on adults. They say it was able to identified tiny but crucial signs of autism only detectable by computer.

The new scanning method picks up on structural changes in the brain's gray matter.

The research team is now looking at whether the test will be effective on children.
