MRI (magnetic resonance imaging) scan

04 May 2011
An MRI scan is similar to a CT scan (see above) but uses magnetism instead of x-rays to build up the pictures. The scan is painless but it can be frightening as the machine is very noisy and the child has to lie in a narrow tunnel. The child may be given a sedative or a general anaesthetic to make sure that they lie still. They will also be given earplugs or headphones to wear.
