Abstract
The use of sedation before a magnetic resonance imaging (MRI) scan is a common practice to overcome motion artifacts and anxiety in children. However, this technique has its drawbacks. We retrospectively compared the number of children undergoing a brain MRI scan with or without sedation before and after the introduction of an educational training protocol using a toy scanner (the Philips Kitten Scanner) and we investigated the effectiveness of this training in relation to children's age and gender. We considered 1461 children between 4 years and 14 years. Of them, 158 had a diagnosis of autism spectrum disorder or attention-deficit hyperactivity disorder and were excluded from further analysis. After the introduction of the Kitten Scanner training protocol, the sedation need decreased by 30% in the total sample group and in children younger than 10 years in particular. Before the training, females were more likely to undergo the MRI examination without sedation as compared to males, while after its introduction this gender difference was no more visible.
