Relaxivities of Gadolinium Heteropoly Complexes in Aqueous Solution for MRI Contrast Agent

LI Jian Xin, CHEN Ya Guang, LIU Qun, SUN Zhen Gang, LIU Jing Fu  [WT5”BX](Department of Chemistry, Northeast Normal University, Changchun 130024, China) [WT5HZ]  
The relaxivities of two gadolinium heteropoly complexes β K 17 [(GdO) 3(SiW 9O 34 ) 2]·20H 2O and K 13 [Gd(GeW 11 O 39 ) 2]·20H 2O in aqueous solution have been measured. Their relaxivities are 16.27 and 16.41 mmol -1 ·s -1 ·L, respectively. The results indicate that the two gadolinium heteropoly complexes may be potential contrast agents for MRI. [WT5HZ]
