Fluorine-18 Labeling of Peptides and Proteins

2006
The pool of promising peptides worthy of investigation and evaluation for clinical use is continuously filled from different sources. Driven by the promising results obtained with peptides addressing somatostatin-2 receptor positive (sst2+) neuroendocrine tumours, other peptides targeting further receptor systems are being studied and evaluated ...

The half-life of fluorine-18

Journal of Inorganic and Nuclear Chemistry, 1964
Radiochemically pure 18F has been prepared by three different methods and its decay has been followed with β proportional counters and γ-ray counters in an effort to measure the half-life accurately. Analysis by a computer program that used the method of least squares gave a weighted mean half-life of 18F and a weighted standard deviation of the mean ...

PET imaging of musculoskeletal tumours with fluorine-18 α-methyltyrosine: comparison with fluorine-18 fluorodeoxyglucose PET

European Journal of Nuclear Medicine, 2000
Fluorine-18 labelled alpha-methyltyrosine (FMT) was developed for positron emission tomography (PET) imaging, and its potential for clinical application in patients with brain tumours has been demonstrated. This is the first trial to compare FMT with 18F-fluoro-2-deoxy-D-glucose (FDG) for the evaluation of musculoskeletal tumours. Seventy-five patients

The value of fluorine-18 for scanning bone tumours

Clinical Radiology, 1969
The mechanisms of uptake of fluorine and strontium by normal as well as abnormal bone are described and the advantages of fluorine for scanning are emphasized. The scanning technique is discussed and a method for accurate reduction in size of the radiographic image to correspond exactly with that of the scan image is described.

Fluorine-18 Fluorodeoxyglucose Uptake in the Retractile Testis

Clinical Nuclear Medicine, 1999
A 51-year-old man with a palpable mass in his right inguinal region had fluorine-18 fluorodeoxyglucose (F-18 FDG) whole-body positron emission tomography (PET) in our cancer screening program. FDG accumulated in the mass, suggesting a metabolically active lesion that was likely malignant.

Synthesis of fluorine-18 labeled 21-fluoroprogesterone

Steroids, 1977
21-Fluoroprogesterone has been synthesized by the nucleophilic displacement of the mesyl group of the 21-hydroxypregn-4-ene-3,20-dione 21-methanesulfonate by fluoride ion, as formed from the solvolysis of potassium fluoride in acetonitrile, using 18-Crown-6 as the catalyst.

[Fluorine-18 in radiopharmacy].

Annales pharmaceutiques francaises, 2008
Positron emission tomography (PET) is a recent and expanding functional nuclear imaging technique. Its extensive development is related to the radiophysical properties fluorine 18 (18F) (weak energy of positron, sufficiently long physical half-life) and to the simple production and labeling procedures for 18F.

Synthesis of the fluorine-18 labeled inhalation anesthetics

Applied Radiation and Isotopes, 1994
Fourteen compounds (fluoroalkanes and fluoroethers), including the two most utilized inhalation anesthetics Isoflurane (CF3CHClOCF2H) and Halothane (CF3CHBrCl), have been labeled with fluorine-18 via a facile 18F-for-19F exchange reaction. The compounds include ten inhalation anesthetics which span a ten-fold range in potency and four structurally ...

Fluorine-18-fluorodeoxyglucose uptake in pneumonia.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1998
Whole-body PET imaging with 18F-fluorodeoxyglucose (FDG) has been shown to be effective in distinguishing benign and malignant pulmonary disease. Mild elevations in FDG uptake with standardized uptake values (SUVs) less than 2.5 have been reported in benign lesions, including pneumonia.
