Terms to Know
Computed Tomographic (CT) Scan

A specialized x-ray device that takes multiple images to create a 3D model of the brain.

Functional MRI (fMRI)

A device like an MRI that uses magnetic field to measure blood flow to areas of the brain over time to measure how it works.

Magnetic Resonance Imaging (MRI)

A device that uses magnetic field to provide images of the internal structures of the brain in 3D.

Neurologic Soft Signs

Minor signs of more non-specific brain disorders, like clumsiness or poor hand-eye coordination.

Positron Emission Tomography (PET) Scan

A device that uses a radioactive fluid, usually attached to glucose, injected into a person to measure which areas of the brain are active.
