Preparing Kids for MRI Using VR

Children frequently exhibit pre-MRI anxiety that can cause motion, repeated sequences, prolonged room time, and exposure to sedation. Orientation with Virtual Reality (VR) may reduce anxiety by familiarizing children with the scanner environment and expected sensations. This single-center, three-arm randomized clinical trial evaluates whether (1) Home+Booster VR (an age-appropriate 360° VR module at home \~24-48 hours before MRI plus a brief on-site refresher immediately before positioning), (2) Pre-Scan VR only (same module viewed on site immediately before positioning), or (3) Usual Care without VR improves MRI image quality and tolerance in children undergoing their first-ever MRI. Eligible participants are children scheduled for clinically indicated, non-emergent MRI with no prior MRI experience. Major exclusions comprise MRI contraindications; contraindications to VR use (e.g., uncontrolled epilepsy or severe motion sickness); uncorrected severe visual/hearing impairment precluding VR viewing; and inability to provide assent/consent. After consent/assent, participants are randomized 1:1:1 to one of three arms. Anticipated enrollment is \~150 total (\~50 per arm; up to 60 per arm if feasible). All arms receive routine safety procedures and child-oriented coaching per institutional practice. The VR module (\~8-10 minutes) provides a 360° walkthrough of the MRI process (sounds, positioning, keeping still) with child-focused narration. Adherence (timestamps/duration) is recorded where applicable. The primary outcome is motion artifact rated on a predefined ordinal scale by a board-certified radiologist masked to allocation; the proportion achieving diagnostic quality without repeat/sedation is also reported. Key secondary outcomes include sedation requirement, number of repeated sequences, total scan room time, scan completion without interruption, and change in child anxiety (mYPAS-SF). Additional prespecified measures include comfort/calmness Likert scales, Wong-Baker FACES pain, CEMS during scan, parent state anxiety, satisfaction VAS, physiologic vitals (heart rate, blood pressure, SpO₂) at defined peri-scan time points, observed crying and movement durations, and total scan duration. The trial uses parallel assignment with allocation concealment and masked outcome assessment. Analyses follow intention-to-treat with prespecified subgroup exploration by age bands (5-7 vs 8-10). Recruitment is planned for October 6, 2025; primary completion is expected within approximately three months.
