Gadolinium is a chemical element; it has symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is a malleable and ductile rare-earth element. Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating. Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic, with ...
MRI contrast agents are contrast agents used to improve the visibility of internal body structures in magnetic resonance imaging (MRI). [1] The most commonly used compounds for contrast enhancement are gadolinium -based contrast agents (GBCAs). Such MRI contrast agents shorten the relaxation times of nuclei within body tissues following oral or ...
Gadolinium (III) chloride, also known as gadolinium trichloride, is GdCl3. 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. Gd 3+ species are of special interest because the ion has the maximum number of unpaired spins possible, at ...
Gadolinium oxide forms on the surface of gadolinium metal. Gadolinium oxide is a rather basic oxide, indicated by its ready reaction with carbon dioxide to give carbonates. It dissolves readily in the common mineral acids with the complication that the oxalate , fluoride, sulfate and phosphate are very insoluble in water and may coat the grains ...
Gadolinium oxysulfide is a promising luminescent host material, because of its high density (7.32 g/cm 3) and high effective atomic number of Gd. These characteristics lead to a high interaction probability for X-ray radiation. Several synthesis routes have been developed for processing Gd 2 O 2 S phosphors, including: solid state reaction ...
Gadopiclenol. Gadopiclenol, sold under the brand name Elucirem among others, is a contrast agent used with magnetic resonance imaging (MRI) to detect and visualize lesions with abnormal vascularity in the central nervous system and in the body. [2][7] Gadopiclenol is a paramagnetic macrocyclic non-ionic complex of gadolinium.
Gadoteric acid, sold under the brand name Dotarem among others, is a macrocycle -structured gadolinium-based MRI contrast agent (GBCA). It consists of the organic acid DOTA as a chelating agent, and gadolinium (Gd 3+), and is used in form of the meglumine salt (gadoterate meglumine). [4][5] The paramagnetic property of gadoteric acid reduces ...
Gadolinium monosulfide. [Gd]. [S] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Gadolinium monosulfide is a binary inorganic compound of gadolinium and sulfur with the chemical formula GdS. [ 1][ 2]
