Neuroimaging Techniques

Neuroimaging techniques are advanced methodologies used to visualize and map brain structure and function, enabling researchers and clinicians to study the central nervous system's anatomy and activity. Common examples include functional magnetic resonance imaging (fMRI), computed tomography (CT), and positron emission tomography (PET).

Key Terms

MRI
Magnetic Resonance Imaging, a technique that uses magnetic fields and radio waves to create detailed images of organs and tissues.

Example: MRI is often used to diagnose brain tumors.

fMRI
Functional Magnetic Resonance Imaging, a type of MRI that measures brain activity by detecting changes in blood flow.

Example: fMRI can show which areas of the brain are active during a task.

CT Scan
Computed Tomography Scan, an imaging method that uses X-rays to create cross-sectional images of the body.

Example: CT scans are commonly used in emergency rooms to assess injuries.

PET Scan
Positron Emission Tomography Scan, an imaging test that helps reveal how tissues and organs are functioning.

Example: PET scans can detect cancer by showing areas of high metabolic activity.

Neuroscience
The scientific study of the nervous system, including the brain.

Example: Neuroscience combines biology, psychology, and chemistry.

Neurodegenerative Disease
A disorder characterized by the progressive degeneration of the structure and function of the nervous system.

Example: Alzheimer's disease is a common neurodegenerative disease.
