摘要：
A dendritic polymer and a magnetic resonance imaging contrast agent employing the same. The magnetic resonance contrast agent includes the dendritic polymer according to the structure of SP-DZ-L)i)j or SP-DX-Z-L)i)j, wherein, S is cyclosilane moiety with j silicon oxygen residual groups, and j is not less than 2 P isand l is not less than 1 D is a C3-30 dendritic moiety having n oxygen residue, and n is not less than 3 X is C3-30 moiety having bi-functional groups Z is a C3-20 moiety having a plurality of functional group and L is a metal cation.
