Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.
Apr 18, 2023 · A positron emission tomography (PET) scan is an imaging test that can help reveal the metabolic or biochemical function of your tissues and organs. The PET scan uses a radioactive drug called a tracer to show both typical and atypical metabolic activity.
Dec 16, 2021 · A positron emission tomography (PET) scan is an imaging test that allows your doctor to check for diseases in your body. The scan uses a special dye containing radioactive tracers. These...
Oct 19, 2022 · A positron emission tomography (PET) scan is an imaging test that produces images of your organs and tissues at work. The test uses a safe, injectable radioactive chemical called a radiotracer and a device called a PET scanner.
What is positron emission tomography (PET)? Positron emission tomography (PET) is a type of nuclear medicine procedure that measures metabolic activity of the cells of body tissues. PET is actually a combination of nuclear medicine and biochemical analysis.
Positron emission tomography (PET) is an advanced medical imaging examination that provides detailed information on the function of an organ or system in your body. It is combined with an anatomical technique such as a computed tomography (CT) or magnetic resonance imaging (MRI) scan at the same time. These techniques allow your doctor to:
Positron emission tomography (PET) uses small amounts of radioactive materials called radiotracers or radiopharmaceuticals, a special camera and a computer to evaluate organ and tissue functions. By identifying changes at the cellular level, PET may detect the early onset of disease before other imaging tests can.
May 7, 2024 · A positron emission tomography (PET) scan detects abnormal cell metabolism to diagnose cancer, heart disease, and brain disorders. Learn about the benefits of a PET scan and possible side effects or risks.
Feb 2, 2023 · A positron emission tomography, or PET, scan is an imaging technique that uses radioactive tracers attached to sugar molecules. The scan can detect changes in the body's metabolism and chemical activities.
