    摘要: The present invention provides a system for evaporating a radioactive fluid, a method for the synthesis of a radiolabelled compound including this system, and a cassette for the synthesis of a radiolabelled compound comprising this system. The present invention provides advantages over known methods for evaporation of a radioactive fluid as it reduces drastically the amount of radioactive gaseous chemicals that are released in the hot cell. It is gentler and more secure compared to the known process and provides access to radiosyntheic processes that may not been acceptable for safety reasons related to release of volatile radioactive gases during evaporation. In addition, the process yields are higher because the radioactive volatiles are labelled intermediate species.

    摘要: The present invention relates to a radiotracer precursor for imaging of hypoxic tissues, a radiotracer and a method for preparing the same. The radiotracer precursor, BANI, includes a nitroimidazole functional group with a feature of retention in hypoxic tissues and a bifunctional ligand able to complex with radioisotopes. Thus BANI can be used to produce radiotracers retained in hypoxic tissues and the radiotracers are applied to medical imaging of malignant tumor with hypoxic layer.
