Abstract: Disclosed is a lymph targeting nuclear magnetic contrast agent using a brown algae polysaccharide as a carrier, and a preparation method and a use thereof. A macromolecular contrast agent with good water solubility was prepared by using the brown algae polysaccharide as the carrier, using mannose or mannose derivatives as a mannose receptor (MBP) recognition group, and using a paramagnetic metal ion chelate as a nuclear magnetic resonance imaging group. The binding capacity of lymphoid tissue was improved. The mannose or mannose derivative group introduced into the synthesized contrast agent molecule achieves the goal of binding to the enriched mannose receptors in the lymphoid tissues. At the same time, after the contrast agent is injected subcutaneously, both lymph vessels and lymph nodes were clearly visualized under MRI scanning.

Abstract: 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.
