Nuclear magnetic resonance imaging (MRI) has become a powerful technique in clinical diagnostics. In this work, a new MRI contrast agent by covalently linking Gd(III) chelates to the side chain of conjugated polymer (PF–Gd) is synthesized by Suzuki cross-coupling reaction. The PF–Gd exhibits a higher relaxivity and a pronounced enhancement in contrast than that of (NMG)2–Gd–DTPA widely used for clinical
核磁共振成像(MRI)已成为临床诊断中的一项强大技术。在这项工作中,通过Suzuki交叉偶联反应合成了一种新的MRI造影剂,它通过将Gd(III)螯合物与共轭聚合物(PF-Gd)的侧链共价连接。与广泛用于临床诊断的(NMG)2 –Gd–DTPA相比,PF–Gd具有更高的松弛度和明显的对比度增强。这项工作应该是可行的,以潜在地导致一类新的成像造影剂。
