Positron emission tomography
Positron emission tomography (PET) is a medical imaging technique that allows visualization and measurement of metabolic processes in the body. It is particularly useful in diagnosing and monitoring diseases such as cancer, cardiovascular diseases, and neurological disorders.
About
It is particularly useful in diagnosing and monitoring diseases such as cancer, cardiovascular diseases, and neurological disorders. PET works by detecting positrons, which are positively charged particles produced by the decay of radioactive substances injected into the body. The positrons collide with electrons, resulting in the emission of two gamma photons that are detected by a PET scanner. These data are then used to reconstruct detailed three-dimensional images of the body's internal organs and tissues, providing valuable information about their function and structure. PET has revolutionized the field of medical imaging by offering a non-invasive method to study early stages of diseases, track treatment response, and guide decisions in personalized medicine.
