Ong YZ, et al. - In this institution review board-approved prospective study, the researchers evaluated the effectiveness of pre-scan videos on the percentage of children requiring general anaesthesia (GA), having repeated magnetic resonance imaging (MRI) sequences due to motion, and having confidence in keeping still for at least 30 minutes during their MRI examinations. For the purpose of this investigation, 786 children between 3 to 21 years old scheduled for MRI were randomised into control, regular cartoon video only, and interactive cum regular cartoon video groups. It was observed that watching videos before scans resulted in a decrease in the requirement for repeated imaging and confidence of children in staying still for scans improved after watching pre-scan videos. It was noted that addition of interactive video had a greater effect when compared to regular cartoon video alone.
