PET Imaging, or Positron Emission Tomography, is a nuclear medicine technique that provides three-dimensional images of functional processes in the body by detecting pairs of gamma rays emitted indirectly by a positron-emitting radiotracer. It is widely used in oncology, neurology, and cardiology to diagnose and monitor diseases by visualizing metabolic activity and molecular pathways.

PET Imaging

Positron Emission Tomography (PET) is a non-invasive imaging technique that allows for the visualization and measurement of metabolic processes in the body by detecting gamma rays emitted from a radioactive tracer injected into the patient. It is widely used in oncology, neurology, and cardiology to assess tissue function and detect diseases such as cancer, Alzheimer's, and heart disease.

Functional processes in the body

Gamma rays are high-energy electromagnetic radiation emitted from atomic nuclei during radioactive decay or other high-energy processes. They have the shortest wavelength and highest frequency in the electromagnetic spectrum, making them extremely penetrating and capable of causing ionization in materials they pass through.

Oncology is the branch of medicine that deals with the prevention, diagnosis, and treatment of cancer. It encompasses a wide range of practices and is constantly evolving with advancements in research and technology to improve patient outcomes.

Oncology

Neurology is the branch of medicine that focuses on the diagnosis and treatment of disorders affecting the nervous system, which includes the brain, spinal cord, and peripheral nerves. It encompasses a wide range of conditions from epilepsy and stroke to multiple sclerosis and neurodegenerative diseases, requiring a multidisciplinary approach for effective management.

Neurology

Cardiology is the branch of medicine that deals with the diagnosis and treatment of heart diseases and conditions. It encompasses a wide range of disorders, including coronary artery disease, heart failure, and arrhythmias, and employs various diagnostic tools and treatments to improve cardiovascular health.

Molecular pathways are a series of interactions among molecules in a cell that lead to a certain product or change in the cell, playing a crucial role in understanding cellular processes and disease mechanisms. They are essential for deciphering complex biological functions and developing targeted therapies in fields like cancer research and pharmacology.
