[en] A novel method for a 11C-C bond formation was developed, employing a cross-coupling reaction between a terminal acetylene and [11C]methyl iodide. The method was used for the synthesis of 17α-([11C]prop-1-ynyl)-3-methoxy-3,17β-estadiol. (orig.)

[en] The suitability of FMcN as a PET tracer was studied in six-week-old piglets. The binding equilibrium in piglet brain was reached about 60 min after i.v. administration of FMcN. The binding was significantly reduced by citalopram but not by maprotiline. It was concluded that FMcN may be suitable for use in humans. (orig.)

[en] A modified procedure for the synthesis of S-[18F-fluoromethyl]-(+)-McN5652 is described. Hydrolysis of the thioester precursor 1 with an aqueous potassium hydroxide solution prevents the formation of a polar side product. Under these conditions the radiochemical yield was increased to 16 ± 4% (corrected for decay and related to starting [18F]fluoride). (orig.)

[en] Aim: characterisation of the influence of different polymeric tube materials of a water target system, used for the production of 18F activity, on the specific activity of radiotracers. Material, methods: target water samples taken from different locations of the 18F water target system of a Cyclone registered 18/9 cyclotron, equipped with Teflon registered (PTFE) or polypropylene (PP) tubes, were analyzed for non-radioactive [19F]fluoride content. [19F]Fluoride content was measured by ion chromatography (IC20, Dinoex) with suppressed conductivity detection. Both the ion chromatographic results and the amount of 18F activity produced were used for the calculation of the specific activity (SA) of [18F]fluoride at the start of the labelling synthesis. To check these results, the SA of the labelled receptor ligand [18F]ZK811460 was also determined by using the different tubing materials. Results: dose-exposed PTFE tubes of the target dispensing (loading) system were identified to be a major source of [19F]fluoride contamination. Conclusion: by replacing PTFE tubes of the target dispensing system with PP tubes, the content of 19F was reduced considerably resulting in an increase of SA of the radiotracer [18F]ZK811460 by factor of two.

[en] At the Rossendorf PET Centre the PET cyclotron and the radiochemical laboratories are 500 m away from each other. The distance is bridged by a radionuclide transport system (RATS) whose details such as layout, technical parameters, control system and radiation protection are described along with our experience in long-distance transport of radionuclides
