Complete table of nuclides Fluorine-18 ( 18 F, also called radiofluorine) is a fluorine radioisotope which is an important source of positrons . It has a mass of 18.0009380(6) u and its half-life is 109.771(20) minutes.
This is less than the decay half-life of any of the fluorine radioisotope nuclear ground states except for mass numbers 14–16, 28, and 31. [9] The half-life of 26m F is 2.2(1) milliseconds; it decays mainly to its ground state of 26 F or (rarely, via beta-minus decay) to one of high excited states of 26 Ne with delayed neutron emission.

The [18 F]FDG-6-phosphate formed when [18 F]FDG enters the cell cannot exit the cell before radioactive decay. As a result, the distribution of [18 F]FDG is a good reflection of the distribution of glucose uptake and phosphorylation by cells in the body. [citation needed] The fluorine in [18 F]FDG decays radioactively via beta-decay to 18 O −.
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.

The U.S. Food and Drug Administration (FDA) approved Fluorodopa F 18 based on evidence from one clinical trial of 56 patients with suspected PS. [3] The trial was conducted at one clinical site in the United States.
In ice cores, mainly Arctic and Antarctic, the ratio of 18 O to 16 O (known as δ 18 O) can be used to determine the temperature of precipitation through time.Assuming that atmospheric circulation and elevation has not changed significantly over the poles, the temperature of ice formation can be calculated as equilibrium fractionation between phases of water that is known for different ...
Florbetaben, sold under the brand name Neuraceq, is a diagnostic radiotracer developed for routine clinical application to visualize β-amyloid plaques in the brain. It is a fluorine-18 (18 F)-labeled stilbene derivative.
