Methods used to study the brain's structure include computed axial tomography (CAT) scans and magnetic resonance imaging (MRI). CAT scans show the size, shape, and position of internal structures by using computer technology to combine a series of X-rays into a detailed image of the skull and brain.
Psychologists study the brain with many different methods. Neuroimaging, or brain scanning, includes the use of various techniques to directly or indirectly image the structure, function, or pharmacology of the brain. It is a relatively new discipline within medicine, neuroscience, and psychology.
Purpose: Provide images of the structure and activity of the brain and body. Pros: Cheap, good at showing overall / average activity level of different regions / structures. Cons: Radiation exposure (X-rays + radioisotope), relatively low detail images, the patient must be lying still on the table.

- Used to measure brain structure - Uses x-rays to create an image of the brain - Can show us abnormalities in structure (swelling or bleeding) but not what areas of the brain are active - Often used in emergency situations
MCAT Neuroimaging Techniques. Get a hint. Computerized Tomography (CT or CAT) structural imaging; creates a three-dimensional "snapshot" of the brain that appears as a series of cross-sectional images; uses a computer to combine topographical images created by X-ray absorption of an anatomical part. 1 / 6.
