Apr 18, 2023 · Overview. Positron emission tomography Enlarge image. 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 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...
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.
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.
PET scans are often used to evaluate and diagnose cancers, neurological (brain) disorders, and cardiovascular (heart) diseases. A PET-CT or PET-MRI scan can provide more information in staging cancer than MRI or CT scans alone. These scans can also show how well a cancer treatment is working.
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.
A positron emission tomography (PET) scan is an imaging test that uses radioactive material to diagnose a variety of diseases such as tumours, heart disease, brain disorders. A PET scan shows how the body is working, unlike other scans, which only show its structure.
Mar 12, 2023 · What Is a PET Scan? 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...
Positron emission tomography (PET) scans produce detailed 3-dimensional images of the inside of the body. The images can clearly show the part of the body being investigated, including any abnormal areas, and can highlight how well certain functions of the body are working.
The PET scan or a positron emission tomography scan is a type of test which uses a mildly radioactive drug to highlight the areas of your body where cells are more active than normal. . When is a PET-CT Scan Needed? PET-CT Scans are used to help doctors diagnose cancer and the stage of the cancer.
