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 These are chemical compounds in which one or more atoms have been replaced by a short-lived, positron emitting radioisotope.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
FDG is used to explore the possibility of cancer spreading to other body sites (cancer metastasis). These FDG PET scans for detecting cancer metastasis are the most common in standard medical care (representing 90% of current scans). The same tracer may also be used for the diagnosis of types of dementia.
Fluoroethyl-l-tyrosine (18 F) commonly known as [18 F]FET, is a radiopharmaceutical tracer used in positron emission tomography (PET) imaging.This synthetic amino acid, labeled with the radioactive isotope fluorine-18, is a valuable radiopharmaceutical tracer for use in neuro-oncology for diagnosing, planning treatment, and following up on brain tumors such as gliomas.
PET is a functional imaging technique that produces a three-dimensional image of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron -emitting radionuclide ( tracer ), which is introduced into the body on a biologically active molecule.
In PET imaging, [18 F]FDG is primarily used for imaging tumors in oncology, where a static [18 F]FDG PET scan is performed and the tumor [18 F]FDG uptake is analyzed in terms of Standardized Uptake Value (SUV). FDG PET/CT can be used for the assessment of glucose metabolism in the heart and the brain.
Since 68 Ga is a positron emitter, 68 Ga-Trivehexin is applicable for PET imaging. However, PET is rarely used as a standalone imaging technique these days. Most clinics use PET/CT or even PET/MRI systems that acquire morphological and functional images in a single workflow and thus, provide more detailed and useful medical information to the ...
“Amyloid PET scans are a proven tool and can be an important part of Alzheimer’s diagnosis and treatment,” Maria Carrillo, chief science officer of the Alzheimer’s Association, said in a ...
Brain positron emission tomography is a form of positron emission tomography (PET) that is used to measure brain metabolism and the distribution of exogenous radiolabeled chemical agents throughout the brain. PET measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream.
