An MRI is generally considered to be safe. Millions of people are scanned in the United States each year. Serious complications can occur if you have an implant or medical device that is not safe to go in the magnetic field of the MRI scanner. A researcher and an MRI Technologist will review safety information prior to your scan. You will be asked several questions about any prior surgeries or medical procedures you have ever had in your life. It is important that you tell them if you have any metallic objects or devices in your body. The MRI Technologist will be in communication with you during your scan. You will also have a “call bell” in your hand so that you can contact the MRI Technologist at any time.
