The regional brain differences in a patient with autism are seen in this computer-generated image of a magnetic resonance imaging (MRI) scan, in this undated handout. A 15-minute brain scan could in future be used to test for autism, helping doctors diagnose the complex condition more cheaply and accurately. British scientists said on Aug 10, 2010, their rapid test had proved more than 90 percent accurate in adults and there was no reason why it should not work equally well in children. The orange and red sections in the picture indicate larger and thicker areas of a brain with autism, while the blue represents areas reduced in size compared to a non-autistic brain. [Agencies]
