  The present invention relates to a novel class of paramagnetic ion-based contrast agents of formula (I), wherein a chelating backbone moiety is highly functionalized by the presence of one or more polyhydroxylated chain, that show a pharmacokinetic profile analogous to that of the commonly used T1-general extravascular agents (NSA) but are further characterized by a higher relaxivity.

  本发明涉及一种新型的基于顺磁离子的对比剂类别，其化学式为(I)，其中螯合骨架部分通过一个或多个多羟基链的存在高度功能化，表现出与常用的T1通用非血管外用对比剂(NSA)相似的药代动力学特征，但具有更高的弛豫度。
