Abstract A new self-assembly gadolinium(III)–iron(II) complex (Gd 2 Fe) was synthesized and characterized. Relaxivity studies showed that complex Gd 2 Fe exhibited higher relaxation efficiency compared with the clinically used Gd-DTPA. In vitro MR images on a 0.5 T magnetic field exhibited a remarkable enhancement of signal contrast for Gd 2 Fe than Gd-DTPA. The results indicated that Gd 2 Fe could
摘要 合成并表征了一种新的自组装钆(III)-铁(II)配合物(Gd 2 Fe)。弛豫研究表明,与临床使用的 Gd-DTPA 相比,配合物 Gd 2 Fe 表现出更高的弛豫效率。在 0.5 T 磁场下的体外 MR 图像显示出 Gd 2 Fe 的信号对比度比 Gd-DTPA 显着增强。结果表明Gd 2 Fe 可以作为潜在的MRI 造影剂。
