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.

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.

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.

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.

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.

2024年6月19日 · PET-CT imaging is a form of dual-modality imaging that utilizes the advantages of both positron emission tomography (PET) and computed tomography (CT). PET imaging excels at detailing physiologic or biologic phenomena through the administration of positron-emitting radiopharmaceuticals.

2024年9月15日 · 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 working. This can help them...

With PET/CT, Stanford doctors can make more accurate diagnoses, develop more targeted treatment plans, and do better, less-invasive treatment monitoring, which should result in improved patient outcomes. A PET/CT scan is noninvasive, painless and takes about 30 minutes.

2024年9月29日 · Positron emission tomography (PET) is a modern non-invasive imaging technique for quantification of radioactivity in vivo.
