Helping children learn about brain scans through play

Many adults find the procedure of having a brain scan, which involves having to lie still for an hour or more while images are analysed, an unsettling experience.
The process is no less daunting for young children, who are usually given a general anaesthetic when they have the procedure.
However, a pilot scheme at University College Hospital in London is helping young people have a scan without being sedated, by teaching them about it through play.
