Magnetic Resonance Imaging (MRI)
MRI is a noninvasive imaging technique that allows us to look inside the brain while kids are doing math.
To create images of the brain's structure and function, MRI scanners use magnetic fields, electric field gradients, and radio waves.
MRI does not involve X-rays or ionizing radiation, and is considered a very safe research method.
When thinking about getting an MRI, there are two important things to consider:
1) Since the MRI is a big magnet, it is very important to never bring metal into the MRI room. Metal objects (e.g., keys, coins, barrettes) will become projectiles, and metal that is inside bodies (e.g., braces, dental crowns, implants) may move or heat up.
2) The scanner is a tight space and makes loud noises, which people may find uncomfortable.
Every precaution is taken to ensure that each MRI scan at Vanderbilt is safe and as comfortable as possible. Children interact with a mock MRI scanner so that they become comfortable with the scanner's size, shape, and noises before going to the real thing. Scan technicians screen children before they are allowed to go into the MRI environment.

Behavioral Testing
We use testing easels to assess math, reading, and other cognitive abilities.
Children play math and reading games, solve logic puzzles, and do math problems.
We use testing easels, computers, iPads, and pencils and paper.
