Brain Scanning

CAT Scans

• Uses X-rays and a computer to create detailed structural images of the inside of the body
• Cross section of the person's brain
• +Useful for revealing abnormal structures in the brain such as tumours or structural damage

• Measures metabolic activity in the brain
• Injected with a small amount of a radioactive substance (most active areas shown as red/yellow and least active…
