Cardiac PET (or cardiac positron emission tomography) is a form of diagnostic imaging in which the presence of heart disease is evaluated using a PET scanner. Intravenous injection of a radiotracer is performed as part of the scan. Commonly used radiotracers are Rubidium-82, Nitrogen-13 ammonia and Oxygen-15 water. [1]
For cardiac scans, combining CT cardiac data with PET metabolic or perfusion data from PET/CT machines may be of clinical value. While there are unresolved issues with using a high-speed CT scan for attenuation correction of cardiac images, many new CT scanners are marketed with PET scanners and can be used to measure myocardial thickening ...
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. Different tracers are used for various imaging ...
Niagara Falls, NY, Nov. 21, 2024 (GLOBE NEWSWIRE) -- Positron Corporation (“Positron” or the “Company”) (OTC: POSC), a leading molecular imaging medical device company offering PET and PET-CT (Positron Emission Tomography/Computed Tomography) imaging systems and clinical services, is pleased to announce its agreement with Upbeat Cardiology Solutions to supply its PET-CT Systems and ...
This is a list of positron emission tomography (PET) radiotracers. These are chemical compounds in which one or more atoms have been replaced by a short-lived, positron emitting radioisotope. Cardiology
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 superposed (co-registered) image.
