MRI is short for Magnetic Resonance Imaging. MRI is a non-invasive procedure that uses magnets to capture a 3D image of the brain. Sometimes MRI scans may be administered with contrast agents or dyes to enhance the visibility of internal tissues. No contrasts are used in the ABCD Study.
Some of the scans will collect “anatomical pictures” of your child’s brain, which show us the physical structures. In other scans, your child will be asked to play different types of games so that we can see your child’s brain working. This type of scan is a functional MRI (fMRI) that allows researchers to visualize which parts of the brain are active and connected during each task. MRI scans do not use radiation or X-rays and they are safe and painless.
