What is PET/CT scanning? Positron emission tomography, also called PET imaging or a PET scan, is a type of nuclear medicine imaging. Nuclear medicine uses small amounts of radioactive material called radiotracers. Doctors use nuclear medicine to diagnose, evaluate, and treat various diseases.

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 ...

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.

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12月11日 · The PET-CT images of a healthy male subject, were provided by G. Chuto - MD. There are four types of images, typically composed of a positron emission tomography combined with a scanner: PET-CT fusion: combining …

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. We're available 24/7. Call us anytime.

Positron emission tomography— computed tomography (PET/CT) provides highly detailed images that can help fine-tune a diagnosis for cancer, heart disease or brain disorders. At Northwestern Medicine, you’ll find the most current advances in PET/CT along with board-certified radiologists* and licensed technologists to guide your exam.

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.

What is PET/CT? Positron Emission Tomography/Computerized Tomography (PET/CT) is an imaging test that produces high resolution pictures of the body's biological functions and anatomic structures. These images show body metabolism and other functions rather than simply the gross anatomy and structure revealed by a standard CT or MRI scan.

Positron emission tomography (PET) is a type of medical imaging called radionuclide scanning. By detecting radiation after a radioactive material is administered, PET creates images that can provide information about a tissue’s function and can help to identify abnormal tissues.
