Information for Participants
Would you like to participate in a study?
If you are interested in participating in an MRI study at our center, refer to the following resources for more information:
- Stanford Department of Psychology
- Stanford Department of Psychiatry
- Stanford Graduate School of Business
- Stanford University School of Education
People with the following implants cannot be scanned and should not enter the MRI area:
- Aneurysm clips(s)
- Cardiac pacemaker
- Implanted cardioverter defibrillator (ICD)
- Electronic implant or device
- Magnetically-activated implant or device
- Neurostimulation system
- Spinal cord stimulator
- Cochlear implant
- Bone growth/bone fusion stimulator
If you have any other medical or electronic devices in your body, please notify the investigator requesting your participation, as any implant may interfere with the exam or possibly pose a risk.
Orthopedic implants generally pose no risk during MRI, unless they have been recently implanted. Anyone who might have metal fragments such as shrapnel in their bodies (especially their eyes) should not go in the MRI unless they have had an X-ray. Dyes used in tattoos may contain iron and could heat up during MRI, but this is rarely a problem. Braces are usually ok, but may distort the images. Very rarely, people feel uncomfortable, or claustrophobic, as a result of lying inside of the magnet bore. If you are concerned that this may be the case for you, please tell the investigator requesting your participation. Although there is no reason to believe that MRI harms the fetus, the effects of a strong magnetic field on fetuses have not been fully investigated. For this reason pregnant, or potentially pregnant, women should not participate in the studies.
