Abstract:
The present invention relates to an improved [18F] labelled synthon composition, wherein the non-radioactive impurities in said composition have been found to be more straightforward to remove than with known compositions comprising said [18F] labelled synthon. The resultant purified [18F] label led synthon therefore can be used in the production of a positron emission tomography (PET) tracer having improved properties for in vivo imaging. The invention also includes methods of imaging and/or diagnosis using the radiopharmaceutical compositions described.
Abstract:
A method of isolating 186Re according to example embodiments may include vaporizing a source compound containing 185Re and 186Re. The vaporized source compound may be ionized to form negatively-charged molecules containing 185Re and 186Re. The negatively-charged molecules may be separated to isolate the negatively-charged molecules containing 186Re. The isolated negatively-charged molecules containing 186Re may be collected with a positively-charged collector. Accordingly, the isolated 186Re may be used to produce therapeutic and/or diagnostic radiopharmaceuticals having higher specific activity.

Abstract:
A system for synthesizing radiopharmaceuticals comprising a stationary process (10) and single use disposable kits (100). The processor has a kit interface (22) with valve actuators and fluidic fittings that interface to a processor interface (102) on the kit containing corresponding rotary valves and fittings. The kit (100) is positioned to the processor with side supports (24) having slots (26) that allow vertical movement of the kit down to support rods (32). Linear actuators (20) translate the kit toward the processor to interface the rotary valves and fittings and, after processing, off the supports (32) so that the kit falls into a container below. Reagent and reactor vessels have a mounting structure (104). Flexible tubing interconnects vales and fittings on the processor interface (102) and vessels on the mounting structure (104). When needed, a reactor vessel heater (42) can be raised and lowered by an actuator (44).
