High-quality imaging is important for effective diagnosis and treatment in pediatrics. In order to obtain such highquality
image, the patient has to be still during the scan, which may or may not require sedation depending on each patient’s condition. This study, conducted at Siriraj Hospital in Bangkok, Thailand, focused on patient factors that influence success of radiologic procedures for patients without sedation. The participants were children aged between 6 to 15 years old. Participants and parents were asked to watch a 5-minute MRI introductory video, which was specially designed for children. Participants would then make decision whether they needed sedation or not. Fifty-five patients were included in this study. There were 37 patients agreed with non-sedation technique. Ninety-four percent of children (35/37) who decided to proceed without sedation,
were able to complete their MRI sessions. Factors identified from this study that determined success in MRI without sedation in 6-15 years old patients were children at aged 11-15 years and children who had previous exposure to MRI without need of
sedation/anesthesia. There was no anesthetic complication in sedation group.
