There are provided NMR contrast agents comprising water-soluble paramagnetic metal chelates, preferably of Cr(III), Fe(III) or Gd (III), wherein the chelating entity is an anilide group containing organic moiety, preferably a compound of formula I
wherein R1 to R5 may represent hydrogen or halogen atoms, optionally halogenated alkyl or alkyoxy groups or carboxyl groups. The agents are especially suitable for use in NMR imaging of the hepatobiliary system.
所提供的 NMR 造影剂包含水溶性顺磁性金属螯合物,最好是 Cr(III)、Fe(III) 或 Gd (III),其中螯合实体是含有有机分子的苯胺基团,最好是式 I 的化合物。
其中 R1 至 R5 可代表氢原子或卤素原子,也可代表卤代烷基或烷氧基或羧基。这些制剂尤其适用于肝胆系统的核磁共振成像。
