The present invention relates to a new class of paramagnetic ion-based contrast agents of molecular weight lower than 3.5 kDa that show a pharmacokinetic profile analogous to that of the commonly used T1-general extravascular agents and that are further characterized by a higher relaxivity.
本发明涉及一种新的顺磁离子基对比剂,其分子量低于3.5 kDa,显示类似于常用的T1通用非血管内对比剂的药代动力学特征,并且具有更高的弛豫度。
