As a free ion, gadolinium is reported often to be highly toxic, but MRI contrast agents are chelated compounds and are considered safe enough to be used in most persons. The toxicity of free gadolinium ions in animals is due to interference with a number of calcium-ion channel dependent processes.
While NSF is a severe form of disease, gadolinium deposition disease (GDD) is a mild variant with pain (e.g. headache), fatigue, and / or gadolinium depositions. [26] As a free solubilized aqueous ion, gadolinium(III) is highly toxic, but the chelated compounds are
It is also supported by subchronic rodent toxicity experiments, which demonstrate a set of gross and microscopic findings similar to those known to be caused by Zn 2+ deficiency. [16] Under the transmetallation hypothesis, we can expect that subtle changes in formulation can affect the intrinsic safety of gadolinium complexes, which is indeed ...
Gadopentetic acid, sold under the brand name Magnevist, is a gadolinium-based MRI contrast agent. [2]It is usually administered as a salt of a complex of gadolinium with DTPA (diethylenetriaminepentacetate) with the chemical formula A 2 [Gd(DTPA)(H 2 O)]; when cation A is the protonated form of the amino sugar meglumine the salt goes under the name "gadopentetate dimeglumine".
After the FDA has banned red dye No.3, you may be wondering which drinks and candies contain it. Here's the full list—plus, when it'll be removed from shelves.

The FDA has banned red dye No. 3, as the synthetic additive is known to cause cancer. Nutritionists Ilana Muhlstein and Robin DeCicco discuss what this means for American health.
Gadolinium(III) chloride, also known as gadolinium trichloride, is GdCl 3. It is a colorless, hygroscopic, water-soluble solid. It is a colorless, hygroscopic, water-soluble solid. The hexahydrate GdCl 3 ∙6H 2 O is commonly encountered and is sometimes also called gadolinium trichloride.
