Tests - MRI

This produces a very detailed image of the brain. Your child has to lie inside a machine, which is like a big tunnel, and can be noisy. The machine uses a big magnet and radio waves to take a picture of the brain, a bit at a time. Then a computer creates the picture. It does not involve X-rays. The scan takes quite a long time (up to 40 minutes) and so many children will need either sedation or a general anaesthetic to help them to lie still. For most children with LKS, the scan appears normal.
