During the exam, it's important to stay still to obtain the clearest images.The MRI scanner will make loud banging noises during the procedure.Children who have difficulty staying still may need sedation, administered either orally or through an IV line.You may receive a contrast solution, usually gadolinium, through an IV to allow the MRI machine to see certain parts of your brain more easily, particularly your blood vessels.There are no risks associated with an MRI itself.
