Positron Emission Tomography (often called PET) is a medical imaging technique. A specially constructed device can show the path and distribution of a weakly radioactive substance. This substance is called tracer. The tracer dissolves in the blood, which will carry it the brain. There, it concentrates around brain structures that are particularly active. A PET scan detects the radioactivity. Obesity, an increasingly common problem in modern societies, results from energy intake chronically exceeding energy expenditure. This imbalance of energy can be triggered by the internal state of the caloric equation (homeostasis) and Positron emission tomography (PET), imaging technique used in diagnosis and biomedical research.
