    摘要: A novel class of chelated radio-labeled polysaccharide derivatives are useful for diagnosing formed, and forming, blood clots in a vascular system. Novel intermediate metal-binding compounds comprise a water-soluble polysaccharide moiety having an average of at least 0.25 anionic groups per monosaccharide unit, and at least one chelating group derived from amino acids, substituted cyclic acid anhydrides, or carbon disulfide. The intermediate compound is then reacted with a radioactive tracer metal compound.
