    • 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 a hydrophilic aliphatic central moiety 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.
    • 本发明涉及一类化合物和含有这些化合物的诊断组合物,其中化合物是含碘化合物。 更具体地说,含碘化合物是含有亲水性脂族中心部分的化合物,允许与其结合的三个碘化苯基的排列。 本发明还涉及这种诊断组合物作为造影剂在诊断成像中的用途,特别是在X射线成像中以及含有这种化合物的造影剂的用途。
