The results of systematic equilibrium, kinetic, and relaxometric investigations carried out on the Mn(2+) complexes of open-chain and AAZTA ligands indicate that the Mn(CDTA) complex has satisfactorily high kinetic inertness (t(1/2) = 12 h at pH = 7.4), which, in turn, may allow its use as a contrast agent in the field of magnetic resonance imaging (as a replacement for Gd(3+)-based agents).
系统平衡、动力学和弛豫研究的结果表明，开链和AAZTA 配体的 Mn(2+)配合物具有令人满意的高动力学惰性（在 pH = 7.4 时，t(1/2) = 12 小时），这反过来又可能使其可用于磁共振成像领域（作为基于 Gd(3+)的试剂的替代品）。
