    • Compounds of formula (I) RA—CO—N(R2)—(CR12)n—N(R5)—RB and salts or optical active isomers thereof, wherein each R1 independently are the same or different and denotes a hydrogen atom, a hydroxyl group, a C1 to C4 straight of branched alkyl group or a C1 to C4 straight of branched oxyalkyl group; R2 denotes a hydrogen atom or a C1 to C4 straight of branched alkyl group; R5 independently are the same or different and denotes a acyl moiety; RA and RB independently are the same or different and denote a triiodinated phenyl group, preferably a 2,4,6-triiodinated phenyl group further substituted by two groups R3 in the 3 and 5 positions wherein each R3 are the same or different and denote a hydrogen atom or a non-ionic hydrophilic moiety, provided that at least one R3 group in the compound of formula (I) is a hydrophilic moiety; and n denotes a positive integer of 1 to 6. 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.

    • 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 two linked iodinated phenyl groups of the general formula R—N(CHO)—X—N(R3)—R wherein X denoted an optionally substituted alkylene group, R3 denotes a hydrogen atom or an acyl function and each R denotes a triiodinated phenyl residue further substituted by hydrophilic moieties. 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,含碘化合物是含有通式R-N(CHO)-X-N(R3)-R的两个连接的碘化苯基的化合物,其中X表示任选取代的亚烷基,R 3表示氢原子或 酰基官能团,每个R表示进一步被亲水部分取代的三碘化苯基残基。 本发明还涉及这种诊断组合物作为造影剂在诊断成像中,特别是在X射线成像中的用途,以及含有这些化合物的造影剂。
