- n. A silvery-white, malleable, ductile, metallic rare-earth element obtained from monazite and bastnaesite and used in improving high-temperature characteristics of iron, chromium, and related alloys. Atomic number 64; atomic weight 157.25; melting point 1,312°C; boiling point approximately 3,000°C; specific gravity from 7.8 to 7.896; valence 3. See Table at element.

- n. A rare earth metallic element of the Lanthanide series, with a characteristic spectrum, found associated with yttrium and other rare earth elements. Symbol, Gd; it has an atomic number of 64, an atomic weight of 157.25 (C=12.011), and a valence of +3.
from The Century Dictionary and Cyclopedia
- n. A supposed new element found with yttrium in gadolinite.
- n. It belongs to the same family as yttrium. Its oxid is white, and its salts are colorless: atomic weight about 156. It perhaps represents a mixture of more than a single element.

The most effective and common of these clinical agents contain a toxic metal called gadolinium, that is sequestered by wrapping the metal in organic molecules called chelates.

The FDA said that drugs known as gadolinium-based contrast agents will carry new warnings on their labels about the risk of nephrogenic systemic fibrosis if the drugs are administered to certain patients with kidney disease.
A contrast agent called gadolinium is often injected so the blood vessels can be seen better.
Zambrano did not want the fluid pumped into his arm required for an MRI called gadolinium) apparently caused Zambrano to be placed on the 15-day DL back in June and he would rather miss one start because of what he is describing as a tired arm than at least two starts he would miss because of the fluid being injected.
Thomsen and his colleagues believed the drug, which contained a toxic metal called gadolinium, was directly linked to the incapacitating illness of their patients.
The drugs contain a magnetic, metallic chemical called gadolinium that travels throughout the heart and other organs to help clarify image quality during scans.
Rare earth alloys include rare-earth ferrosilicon—with 17%-37% rare-earth content—which is used as an additive in steel and iron smelting, and magnesium rare earth, which contains 2%-10% of rare-earth elements yttrium and gadolinium and is used in the aviation, automotive and defense sectors.

There are seven gadolinium-based contrast agents and they are used to help detect problems with body organs, blood vessels and other tissues.
