Key Concepts

Positron Emission Tomography (PET)

PET is a nuclear medicine imaging technique that involves the injection of radioactive tracers. These tracers emit positrons that are detected to create images, enabling the examination of metabolic processes and molecular activity in tissues, particularly useful for assessing brain function.

Functional Brain Imaging

Functional brain imaging refers to techniques that measure brain activity, rather than just structure. This concept is crucial for mapping areas of the brain involved in specific cognitive or physiological processes, as it helps researchers understand the dynamic functions of different brain regions.
