Functional imaging is a medical imaging technique that measures and visualizes physiological activities within the body, such as blood flow, metabolism, and neural activity, rather than just its structure. It is instrumental in diagnosing diseases, understanding brain functions, and guiding treatment plans by providing dynamic insights into organ and tissue functions.

physiological activities

Blood flow refers to the movement of blood through the circulatory system, driven by the heart's pumping action and regulated by blood vessel constriction and dilation. It is essential for delivering oxygen and nutrients to tissues and organs while removing waste products, maintaining homeostasis and supporting overall health.

blood flow

Metabolism is the set of life-sustaining chemical reactions in organisms that enable them to grow, reproduce, maintain their structures, and respond to environmental changes. It involves two main processes: catabolism, which breaks down molecules to produce energy, and anabolism, which uses energy to construct components of cells such as proteins and nucleic acids.

metabolism

Neural activity refers to the electrical and chemical processes that occur within neurons as they communicate with each other, forming the basis of all brain functions and behaviors. Understanding neural activity is crucial for deciphering how the brain processes information, responds to stimuli, and maintains homeostasis.

The brain is a complex organ responsible for processing sensory information, regulating physiological processes, and enabling cognitive functions such as thinking, memory, and emotion. It operates through intricate networks of neurons and synapses, which communicate via electrical and chemical signals to coordinate bodily functions and behaviors.
