Brain imaging techniques provide critical insights into the brain's structure, function, and chemistry. These methods are vital for diagnosing brain disorders and advancing our understanding of how the brain works.
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.
CT. Purpose: Provide images of the structure of the brain and body. Pros: Cheap, very fast. Cons: Radiation exposure (X-rays), relatively low detail images, no information regarding brain activity, the patient must be lying still on the table.
• Neuroimaging, or brain scanning, includes the use of various techniques to either directly or indirectly image the structure, function, or pharmacology of the brain. • Neuroimaging falls into two broad categories: structural imaging and functional imaging.
- 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.
