What is a brain scan?

Also known as: brain and nerve test, neuroimaging.

A brain scan is an imaging technique that evaluates brain structure and/or function (by detecting blood flow) of the brain. Magnetic resonance imaging (MRI) or computerized tomography (CT) are the two most common types of brain scans, but others may also be used.
