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.
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.
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.
In order for researchers and physicians to study and diagnose the brain for certain diseases, there are a variety of brain imaging techniques that can be used! We’ll cover some of the main ones that maybe you’ve undergone at some point in life!
• Positron emission tomography (PET) scans show brain processes by using the sugar glucose in the brain to illustrate where neurons are firing. • Magnetic resonance imaging (MRI) scans use echo waves to discriminate among grey matter, white matter, and cerebrospinal fluid. Key Terms
