Abstract
BackgroundSimulation using a mock scanner preparation is beneficial for pediatric patients undergoing magnetic resonance imaging (MRI) without sedation for the assessment of neurocognitive function. However, using a simulation protocol for improving the completion of pediatric MRI has not been studied extensively. MethodsA simulation protocol using a mock scanner “Zero-Tesla” preparation immediately before 3T MRI was utilized based on participants’ demographics. The success rate of each protocol step was compared between children with typical development (TD) and those with neurodevelopmental disorders (NDDs). ResultsTwo-hundred forty-one children (4-17 years; 152 males, 89 females; 42.3% TD and 57.7% NDDs) were included. Acceptable MRI qualities were obtained for 100 (98.0%) and 130 (93.5%) children in the TD and NDD groups, respectively. In the NDD group, Zero-T application rates were higher in the young childhood (TD vs NDD; 2% vs 56%, p < .001), middle childhood (5% vs 38%, p < .01), and adolescence (0% vs 49%, p < .001) subgroups than those in the TD group. ConclusionsUse of a simulation protocol could contribute to the successful completion of advanced MRI without sedation in children with TD and NDDs.
