Audiovisual Distraction Increases Success Rates of Sedation‐Free Pediatric Magnetic Resonance Imaging
Main finding · Unsedated MRI successResult — go to the resultOdds ratio 3.68 95% CI 2.24–5.62Authors' conclusion
AV-MRI technology increases the success rate of sedation-free MRI in pediatric patients, reducing risks and healthcare costs without compromising diagnostic quality. Age and sex are important predictors of success.
Study context
- Population
- Pediatric Magnetic Resonance Imaging (MRI) records, November 2015 to March 2017
- Participants

Sex and behavioral issues as predictors
- Female children more likely to complete unsedated scans than males
- Children with behavioral issues less likely to complete an unsedated scan
Motion artifacts, brain MRI (4-point scale; 102 patients), unsedated vs sedated
- More motion in unsedated scans, but all were diagnostic
