Methods: We examined the number of MRI examinations, by inpatient and outpatient, age, and sex for the NDB Open Data Japan from 2014 to 2018. In addition, MRI examination data extracted from the NDB random Sampling Data of outpatient clinics from 2011 to 2015, were classified into the sedation and non-sedation groups and were compared between the two groups. Results: According to the NDB Open Data, approximately 14.61 million MRI examinations are performed in Japan annually, 84.3% of which are performed in outpatient clinics. According to the NDB random Sampling Data, of the MRI examinations performed in outpatient clinics, sedatives were used in approximately 0.61% of cases, most of which were performed on children younger than 10 years. Data aggregated by age revealed that the percentage of children undergoing sedation for MRI was 79.4% for children aged 0-12 months, 79.5% for those aged 1 year, 70.0% for those aged 2 years, 67.7% for those aged 3 years, 54.8% for those aged 4 years, 48.6% for those aged 5 years, and 14.3% for those aged 6 years. There was a decreasing trend in the use of sedative drugs by gender, i. e., for each year of growth, this trend increased 0.56 fold in boys and 0.45 fold in girls. The most commonly used sedative drugs in outpatient clinics were oral medications (65.0%), intravenous drugs (16.5%), suppositories (16.1%), and inhalation anesthetics (1.8%), with no gender difference. The most common oral medication given was 10% triclofos sodium syrup. Conclusions: The current status of pediatric sedation for MRI examinations in Japan, particularly in outpatient clinics, was elucidated. It is essential to take this result into consideration in medical practice.
