What is fdg-pet?

FDG-PET (Fluorodeoxyglucose Positron Emission Tomography) is a medical imaging technique that provides information about the metabolic activity of cells in the body. It is commonly used in oncology to detect and stage cancer, but it can also be used to diagnose and manage other conditions such as neurological disorders and cardiovascular disease.

During an FDG-PET scan, the patient is injected with a radioactive tracer called FDG, which is taken up by cells that use glucose for energy. The tracer emits positrons, which are detected by the PET scanner and used to create an image of the body. Areas of high metabolic activity appear as bright spots on the scan, indicating an increased uptake of the tracer.

FDG-PET is a non-invasive diagnostic tool that can provide valuable information about the location and extent of disease, as well as the response to treatment. It is often used in combination with other imaging techniques such as CT or MRI to provide a more complete picture of the disease. FDG-PET has revolutionized the diagnosis and management of cancer and has become an essential tool in oncology.
