Potential Risks & Discomforts with MRI


 

Potential Risks & Discomforts with MRI

 

There are no known risks to you from psychological testing or interviewing; however, you may get tired or feel nervous if questions are asked that you cannot or wish not to answer. If this occurs, you will be allowed to take a break or ask questions. Under no circumstances will you be pressured to respond.

 

The MRI scanning procedure requires that you be lying in a small, partially-enclosed space.  Some people find this to be uncomfortable and may feel symptoms of claustrophobia including nervousness, sweating or other minor discomfort.  You will be provided with a special ball (or button) to squeeze should you become anxious or agitated during the MRI session.  Squeezing the ball will set off an alarm bell and the MRI scan will be immediately discontinued.  The sound of the MRI scanner can be quite loud; you will be given special earplugs and/or headphones to minimize the noise.  The magnetism of the machine attracts certain metals; therefore, people with these metals in their bodies (such as pacemakers, infusion pumps, aneurysm clips, metal prostheses, joints, rods, or plates) will be excluded from the study.  The metal in most dental fillings is less responsive to magnetism and is therefore allowed.  You will be asked to fill out a metal screening form before you can undergo an MRI scan in order to notify the investigator conducting the study of any metal in your body, other than dental fillings.  There are no other known side effects resulting from exposure to the MRI scan.  In the studies performed so far, there have been no significant risks reported in animals or humans for similar exposures.  However, the potential risks to a fetus are unknown.  Thus, if you are pregnant, or you think you may be pregnant, you should not participate in this study.
