Isotopes of gadolinium (64Gd) Naturally occurring gadolinium (64 Gd) is composed of 6 stable isotopes, 154 Gd, 155 Gd, 156 Gd, 157 Gd, 158 Gd and 160 Gd, and 1 radioisotope, 152 Gd, with 158 Gd being the most abundant (24.84% natural abundance). The predicted double beta decay of 160 Gd has never been observed; only a lower limit on its half ...
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 ...
Gadolinium (III) containing MRI contrast agents (often termed simply "gado" or "gad") are the most commonly used for enhancement of vessels in MR angiography or for brain tumor enhancement associated with the degradation of the blood–brain barrier (BBB). [3][4] Over 450 million doses have been administered worldwide from 1988 to 2017. [5]
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 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 ...
Neutron capture therapy is a binary system that consists of two separate components to achieve its therapeutic effect. Each component in itself is non-tumoricidal, but when combined they can be highly lethal to cancer cells. 1) Boron compound (b) is selectively absorbed by cancer cell (s).
Gadodiamide is a contrast medium used for cranial and spinal magnetic resonance imaging (MRI) and for general MRI of the body after intravenous administration. It provides contrast enhancement and facilitates visualisation of abnormal structures or lesions in various parts of the body including the central nervous system (CNS).
