Fluorine-18 is the most frequently used radioisotope in positron emission tomography (PET) radiopharmaceuticals in both clinical and preclinical research. Its physical and nuclear characteristics (97% β+ decay, 109.7 min half-life, 635 keV positron energy), along with high specific activity and ease of large scale production, make it an attractive nuclide for radiochemical labeling and molecular imaging.

Nucleophilic fluorination (“F-”) i Fluorine-18 is one of the most important isotope in present day positron emission tomography (PET). It assumes greater significance in ready availability of fluorine-18 labelled 2-fluoro-2-deoxyglugose popularly known as FDG in tumour imaging and glucose metabolism studies. Learn how using tools such as PET, PSMA, Fluorine-18, and AI systems could improve prostate cancer detection and lead to more informed decisions.

Pet fluorine 18

Particularly, 18 F‐labeled radiopharmaceuticals play a pivotal role in positron emission tomography (PET), given that fluorine‐18 exhibits favorable characteristics including an optimal half‐life of 109.8 minutes, which allows multistep synthesis and satellite distribution, concurrently limiting radiation burden for the patient. Fluorine-18 is the most important radionuclide used in positron emission tomography (PET) today, largely due to its attractive physical and nuclear characteristics. Agents such as the clinical oncology tracer 2-[18F]fluoro-2-deoxy-D-glucose ([18F]FDG), the most widely used PET-radiopharmaceutical, are driving an increasing interest in the chemistry of radiopharmaceuticals utilizing fluorine-18. A fully automated synthesis of fluorine-18 tracers suitable for positron emission tomography. Since the development of positron emission tomography (PET) in the 1970s, it has become This thesi s deals with the synthesis and evaluation of novel fluorine-18 labeled PET radioligan ds for detection of MAO-B activity.
