Abstract:
The present invention relates to a class of compounds and to diagnostic compositions containing such compounds where the compounds are iodine containing compounds. More specifically the iodine containing compounds are chemical compounds containing an aliphatic central moiety containing amide functions allowing for the arrangement of three iodinated phenyl groups bound thereto. The invention also relates to the use of such diagnostic compositions as contrast agents in diagnostic imaging and in particular in X-ray imaging and to contrast media containing such compounds.
Abstract:
A method for visualizing biological material, preferably by MRI, comprising the steps of: (i) bringing a population of coated nanoparticles into contact with said biological material, each of which nanoparticles comprises a) a metal oxide of a transition metal, said metal oxide preferably being paramagnetic and preferably comprising a lanthanide (+III) such as gadolinium (+III), and b) a coating covering the surface of the core particle, and (ii) recording the image; wherein the coating is hydrophilic and comprises a silane layer which is located next to the surface of the core particle and comprises one or more different silane groups which each comprises an organic group R and a silane-siloxane linkage where a) R comprises a hydrophilic organic group R′ and a hydrophobic spacer B, b) O is oxygen directly binding to a surface metal ion of the metal oxide, and c) C is carbon and is also part of B. A composition for visualization and methods for the manufacture of the nanoparticles and core particles are also disclosed. Visualization includes imaging by MR, CT, X-ray, near IR fluorescence, PET, microscopying etc with the largest advantages accomplished for in-vivo imaging.
