A multi-stream optical interrogation flow cell (60) for a radiopharmaceutical includes a multiple flow cell body (10a-f) defining a first elongate fluid flowpath (A1-6;B1-6) therethrough for individually conducting a radiopharmaceutical therethrough in fluid isolation from other of the flow cell bodies. Each flow cell body further defines a first and second aligned UV transparent optical guides (36,38) and a first interrogation passageway (26a-f) extending between the first and second optical guides such that a portion of the elongate first fluid flowpath intersects the interrogation passageway such that the radiopharmaceutical flows in between the first and second optical guides. The first and second interrogation passageways of all of the flow cell bodies are optically aligned so that a single interrogation beam is able to extend through each of the interrogation passageways.

An HPLC module utilizes a combination of compound-dedicated hardware providing line clearance between differing radiosynthesis and includes multiple compound-dedicated HPLC inject valves, each inject valve directing a fluid to a serially-connected HPLC column and UV flowcell so as to prevent cross-contamination between differing radiopharmaceutical syntheses. The module provides a disposable fluid path from each UV flowcell allowing for radioactive detection, fraction collection, formulation and final product dispensing. In this manner, a level of GMP compliance is achieved that is suitable for meeting the requirements of an MHRA approved site-license.

In one aspect, systems, methods and apparatus are provided through which a dispensing station dispenses a large quantity of a radiotracer to one or more positron emission tomography imaging stations. In some aspects a quality control unit verifies the quality of the radiotracer. In some embodiments, components of the system are coupled by a local area network. In some aspects, each positron emission tomography imaging station includes an injector system, a physiological monitoring device, and a positron emission tomography scanner. All of the devices can be controlled by a computer system.

A process is provided for producing a labeled precursor which is useful for production of a radioactive fluorine-labeled amino acid compound. In the reaction step for introducing a leaving group to a mixture of syn-form and anti-form of FACBC, a base is allowed to present in the reaction system to produce a syn-leaving group adduct, which is unreactive with the base and is highly stable, and an anti-leaving group adduct which can react with the base to form a water-soluble compound. By employing a purification method utilizing such a difference in solubility, the syn-leaving group adduct can be separated selectively. The base may be a linear- or branched-chain primary to tertiary alkylamine having 1 to 10 carbon atoms, a nitrogen-containing heterocyclic compound with 2 to 20 carbon atoms, and a nitrogen-containing hetero aromatic compound with 2 to 20 carbon atoms.

A diagnostic formulation is provided comprising a tropane having a radioactive concentration of at least 1.6 mCi/mL at least about 51 hours post creation. The diagnostic formulation optionally comprises a radiolabeled dopamine transporter (DAT) ligand useful in the diagnosis of Parkinson's disease (PS). One example of a radiolabeled dopamine transporter (DAT) ligand example is [123I]-2β-carbomethoxy-3β-(4-flurophenyl)-N-(3-iodo-E-allyl) nortropane.
