Kitten Scanner reduces the use of sedation in pediatric MRI

Area of Science:

• Pediatric Radiology
• Medical Education

Background:

• Sedation is frequently used for pediatric MRI scans to mitigate motion artifacts and anxiety.
• However, sedation carries inherent risks and drawbacks.
• Alternative strategies to reduce sedation are needed.

Purpose of the Study:

• To evaluate the effectiveness of an educational training protocol using a toy scanner (Kitten Scanner) in reducing sedation for pediatric brain MRI.
• To assess the impact of this training on children's age and gender.

Main Methods:

• Retrospective analysis of 1461 children (aged 4-14) undergoing brain MRI.
• Comparison of sedation rates before and after implementation of the Kitten Scanner training protocol.
• Exclusion of 158 children with autism spectrum disorder or ADHD from analysis.

Main Results:

• The Kitten Scanner training protocol led to a 30% decrease in sedation use for pediatric brain MRI.
• The reduction in sedation was particularly notable in children younger than 10 years.
• Pre-training, females were less likely to require sedation than males; this gender difference disappeared post-training.

Conclusions:

• The toy scanner training protocol is an effective method for reducing sedation requirements in pediatric MRI.
• This educational intervention improves patient management and addresses gender-related disparities in care.
• The findings support the integration of simulation-based training in pediatric radiology practices.
