Gadolinium - Questions and Answers in MRI
The powerful paramagnetic properties of Gd make it extremely useful as an MR contrast agent. Gadolinium is not directly seen in an MR image, but manifests its presence indirectly by facilitating the relaxation of nearby hydrogen protons. Gd preferentially shortens T1 values in tissues where it accumulates rendering them bright on T1-weighted ...

2023年7月3日 · Gadolinium-based contrast agents are paramagnetic, that is, these atoms act like ferromagnetic and superparamagnetic substances, and have a positive magnetic susceptibility. The effect of paramagnetic substances is several order of magnitude weaker than that of other substances with positive susceptibility.
Magnetism of Gadolinium: A First-Principles Perspective
2015年8月26日 · By calculating the spectral density of states in the ferromagnetic ground state and in the high temperature paramagnetic phase we provide the first concise study of finite temperature effects on the electronic structure of the bulk and the surface of gadolinium metal.
Gadolinium - Wikipedia
Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic, with an attraction to a magnetic field higher than that of nickel. Above this temperature it is the most paramagnetic element. It is found in nature only in an oxidized form.

In this paper, we rely on the well-stablished magnetic properties of Gd3+to shed light on this matter. GdOH thin lms present paramagnetic behaviour similar to other Gd3+compounds such as Gd. 2O3.
Gadolinium - Medical Imaging Source
Gadolinium is a paramagnetic element, meaning it becomes partially magnetized when exposed to a strong external magnetic field. This property is essential for creating contrast in MRI images by temporarily modifying the magnetic environment around tissues.
