view. talk. edit. 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-life of more ...
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 ...
Fields. Chemistry. Jean Charles Galissard de Marignac (24 April 1817 – 15 April 1894) was a Swiss chemist whose work with atomic weights suggested the possibility of isotopes and the packing fraction of nuclei. His study of the rare earth elements led to his discovery of ytterbium in 1878 and co-discovery of gadolinium in 1880. [1][2][3]
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body.
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]

Nephrogenic systemic fibrosis is a rare syndrome that involves fibrosis of the skin, joints, eyes, and internal organs. NSF is caused by exposure to gadolinium in gadolinium-based MRI contrast agents (GBCAs) in patients with impaired kidney function. [1][2] Epidemiological studies suggest that the incidence of NSF is unrelated to gender or ...
