Abstract

Manganese ferrite nanoparticles are superparamagnetic and have very high saturation magnetization, which makes them candidates for application as MRI contrast agents. Because these nanoparticles are very effective enhancers of transverse relaxation, they are particularly suitable as negative (T₂-weighted) contrast agents. The magnitude of the relaxivity of nanoparticulate Mn ferrites seems to be determined mainly by the method of preparation, their dimensions, and their saturation magnetization.

铁酸锰纳米颗粒的弛豫率

锰铁氧体纳米颗粒是超顺磁性的，具有很高的饱和磁化强度，这使它们成为MRI造影剂的候选应用。因为这些纳米颗粒是非常有效的横向弛豫增强剂，它们特别适合作为负(t2加权)造影剂。纳米Mn铁氧体的弛豫大小似乎主要取决于制备方法、尺寸和饱和磁化强度。
