Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single ...

During a positron emission tomography (PET) scan, you lie on a narrow table that slides into a doughnut-shaped hole. The scanner takes about 30 minutes to produce detailed images of metabolic activity in your tissues and organs.

2021年10月29日 · Learn how a PET/CT scan is used for cancer diagnosis and treatment, how long it takes, what it shows, and the benefits and risks of this type of imaging.

2022年10月19日 · Positron emission tomography (PET) scans detect early signs of cancer, heart disease and brain conditions. It involves an injection of a safe radioactive tracer that helps detect diseased cells.

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.

Current and accurate information for patients about PET/CT. Learn what you might experience, how to prepare for the exam, benefits, risks and much more.

2024年10月13日 · Positron emission tomography (PET) is an imaging test that detects changes in metabolism and your body's biochemistry. The patterns of these changes can help diagnose different diseases. PET scans use various radioactive drugs called radiotracers that are injected into your bloodstream.

2023年7月1日 · CT scans and PET scans are important tools for medical imaging with specific benefits, uses, risks, and limitations. From the broadest perspective, CT scans help detect structural abnormalities in the body, while PET scans detect functional abnormalities in the body.

A PET-CT scan combines a CT scan and a PET scan. It gives detailed information about your cancer. The CT scan takes a series of x-rays from all around your body and puts them …

Learn about PET/CT, a vital imaging technique combining Positron Emission Tomography (PET) and Computed Tomography (CT), used for diagnosing and monitoring various conditions such as cancer and heart disease. Explore how PET/CT works and its benefits for patients.
