Frequently Asked Questions

IS MY CHILD ELIGIBLE FOR THIS STUDY?

In order to participate, teenage participants must be between the ages of 13-17, live in the same household as their parents, be right-handed, and have no metal on or in their bodies that cannot be removed (nonremovable piercings, orthodontic work like braces or permanent retainers, pacemakers, and clips). In addition, results from a brief, online questionnaire will help us to determine if your teen will be able to participate.

IS IT SAFE TO HAVE AN MRI?

There are no known or foreseeable risks or side effects associated with MRI scanning procedures except for those people who have electrically, magnetically or mechanically activated implants, or metal in or on their bodies. Because the MRI machine has a large magnet inside, it will react to any metal, magnetic material on the participant. Therefore, if an individual has any magnetic material that cannot be removed (for instance, due to prior surgery) he or she will not be able to participate.

MRI scanning involves recording images of your child’s brain using functional magnetic resonance imaging, or fMRI for short. The MRI does not use any radiation (such as x-rays or radioactivity) and your adolescent will not have any type of injections. Images of the brain are created from information obtained by detecting signals from water and other naturally occurring molecules in the brain.

CAN THE MRI TELL ME ANYTHING ABOUT MY CHILD’S BRAIN?

The type of scan in this study is not a medical test. It is designed to address research questions and it is not a complete scan for any clinical purpose. If there is an abnormality in the scan, the MRI technician or the researcher may not detect it. If the technician or researcher suspects a possible abnormality, the scan will be sent without any participant identification to a neuroradiologist for further review. If the neuroradiologist recommends further action, you will be notified by Dr. Alexander Shackman.
