摘要:
The invention relates to the use of perfluoroalkyl-containing metal complexes that have a critical micelle formation concentration 1 nm and a proton relaxivity in plasma (R1)>10 l/mmol·s as contrast media in MR imaging for visualization of intravascular thrombi.
摘要:
Oligomeric compounds that contain perfluoroalkyl of general formula IA--R.sup.F (I)in whichA is a molecule portion that contains 2-6 metal complexes that are connected directly or via a linker to a nitrogen atom of an annular skeleton chain, andR.sup.F is a perfluorinated, straight-chain or branched carbon chain with formula --C.sub.n F.sub.2n E, in which E represents a terminal fluorine, chlorine, bromine, iodine, or hydrogen atom and n stands for numbers 4-30,are valuable compounds for diagnosis, especially as in-vivo contrast media.
