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.

3 days ago · A positron emission tomography (PET) scan is an imaging test that can help reveal the metabolic or biochemical function of the body's tissues and organs. The PET scan uses a radioactive drug called a tracer to show both typical and atypical metabolic activity.

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, …

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.

Oct 13, 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.

Sep 15, 2024 · What Is a PET Scan? A positron emission tomography (PET) scan is a type of imaging study that can help doctors see what’s happening inside your body and how it’s...

PET scan images can detect cellular changes in organs and tissues earlier than other imaging tests such as CT scans and MRIs. Why Do I Need a PET Scan? You may be prescribed a PET scan if your doctor wants to look more closely at:

What is a PET scan? A PET (positron emission tomography) scan is a nuclear imaging test that looks at how well your tissues and organs are working. It also checks for signs of cancer. For the scan, you will get an injection of a small amount of a tracer, which is a safe radioactive substance.

Newer technology combines PET and CT into one scanner, known as PET/CT. PET/CT shows particular promise in the diagnosis and treatment of lung cancer, evaluating epilepsy, Alzheimer's disease and coronary artery disease.

Nov 22, 2023 · What are PET scans, and what are their uses? Vs. CT and MRI. Positron emission tomography (PET) scan uses radiation to show activity in the body on a cellular level. It can help detect...
