Development of Zr-based alloys to suppress MRI artifacts for biomedical applications

锆基合金和复合材料的开发，以抑制MRI伪影在这项研究中。含Nb或Mo的Zr合金的磁化率根据相组成和体积分数而变化。磁化率受负磁化率Ag的积分控制。我们发现，伪影体积减少，减少磁化率定量。因此，开发的锆基合金和复合材料可以减少MRI伪影。

Zr-based alloys and composites were developed to suppress the MRI artifacts in this study. Magnetic susceptibility of Zr alloys containing Nb or Mo varied depending on the phase constitution and the volume fraction. Also, the magnetic susceptibility was controlled by the integration of Ag which was negative magnetic susceptibility. We showed that artifact volume decreased with decreasing magnetic susceptibility quantitatively. Therefore the developed Zr-based alloy and composites can decrease MRI artifacts.
