Development of non-magnetic composite wire materials for preventing artifacts in MRI

本研究开发了一种用于磁共振成像（MRI）中防止伪影的非磁性复合丝材料。研究了顺磁性Zr和反磁性Ag复合丝材的磁化率和力学性能。Zr/Ag复合丝的磁化率约为Ti的10%，磁共振图像伪影较Ti减少。因此，这些Zr/Ag复合线材料可用于MRI下的医疗装置。

This research developed of non-magnetic composite wire materials for preventing artifacts in Magnetic resonance imaging (MRI). The magnetic susceptibility and mechanical property of the composite wire with paramagnetic Zr and diamagnetic Ag were evaluated. The magnetic susceptibility of Zr/Ag composite wire noted almost 10% that of Ti, theartifact of MR image of Zr/Ag composite wire was decreased than Ti. Thus these Zr/Ag composite wire materials are useful for medical devices under MRI.
