 Background, the experience of undergoing magnetic resonance imaging, MRI, can be anxiety-provoking, particularly for pediatric patients and their families. Therefore, alternative methods to improve success and experiences without the use of sedation are needed. Objective, this study aims to compare the effectiveness of a virtual reality, VR, based simulation app, VR MRI, with a standard preparatory manual, SPM, and a hospital-based child life program, CLP, on success and anxiety during a simulated pediatric MRI scan. Additionally, the secondary aim is to compare caregivers' reported anxiety, procedural data, caregiver usability, child satisfaction, and fun. Methods, this unblind.
