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.
The scanner detects diseased cells that absorb large amounts of the radiotracer, which indicates a potential health problem. Healthcare providers frequently use PET scans to help diagnose cancer and assess cancer treatment. They can also assess certain heart and brain issues with the scan.
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 absorb the tracer and...
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.
May 7, 2024 · A PET scan is an imaging test that can help detect diseases based on changes in your body's metabolism. It involves a radioactive tracer that is injected into your bloodstream. The scanner measures metabolic activity based on how much or little of the tracer is taken up by cells.
Apr 27, 2015 · What is a PET scan? A PET scan uses a radiotracer to measure things like blood flow, oxygen use and sugar metabolism. A PET scan shows how your tissues and organs are functioning. It also can let you and your doctors know if cancer treatment is working. Follow your PET scan prep for best results.
Positron emission tomography, also called PET imaging or a PET scan, is a diagnostic examination that involves getting images of the body based on the detection of radiation from the emission of positrons. Positrons are tiny particles emitted from a radioactive substance administered to the patient. Patient Safety Tips Prior to the Exam.
