    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 wherein, P is CH2CH2O1, and 1 is not less than 1 and j is not less than 2; D is a C3-30 dendritic moiety having n oxygen residue, and n is not less than 3 and i is more than 1; X is C3-30 moiety having bi-functional groups; Z is independent and includes a C3-20 moiety having a plurality of functional group, wherein the functional groups are selected from a group consisting of carbonyl, carboxyl, amine, ester, amide, or chelate group, and Z respectively bonds with X by a group; and L is a metal cation.
