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
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.
Dec 16, 2021 · A PET scan is an imaging test that lets your doctor check for diseases in your body. The scan uses a special dye containing radioactive tracers. Certain organs and tissues...
Positron emission tomography ( PET) [1] 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.
Mar 12, 2023 · A PET scan (also known as positron emission tomography and PET/CT) is a type of imaging study that can show doctors what’s happening in your body and how it’s working. It’s different...
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.
PET is a type of nuclear medicine procedure that measures metabolic activity of the cells of body tissues. Used mostly in patients with brain or heart conditions and cancer, PET helps to visualize the biochemical changes taking place in the body.
Jul 26, 2021 · A PET scan is an imaging test that uses a radioactive substance (tracer) to check for changes in chemical activity in the body. This activity may be a sign of cancer, heart disease, or a brain disorder.
Nov 22, 2023 · A PET scan is a radiation-based test that can help a doctor see the inside of a person’s body and assist in the diagnosis of a variety of conditions.
A PET scan is a test doctors use to take pictures of your organs and tissues. First, doctors inject you with a tiny amount of a radioactive substance (a tracer). The tracer is attached to a chemical your body uses, such as sugar (glucose). A large donut-shaped machine then takes scans of your body as it uses the tracer.
