Your child is having an MRI scan using 'feed and wrap' technique

An MRI (magnetic resonance imaging) scan uses a magnetic field rather than X-rays to take pictures of your child’s body. The MRI scanner is a hollow machine with a tube running horizontally through its middle. ‘Feed and wrap’ is a technique used with young babies instead of sedation or general anaesthesia. Generally, babies tend to fall asleep after a feed, so we take advantage of this and scan them while asleep.
