  3. Gadolinium - Wikipedia

    en.wikipedia.org/wiki/Gadolinium

    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 ...

    en.wikipedia.org/wiki/Isotopes_of_gadolinium

    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 ...

  5. MRI contrast agent - Wikipedia

    en.wikipedia.org/wiki/MRI_contrast_agent

    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 ...

    en.wikipedia.org/wiki/Gadolinium_gallium_garnet

    Gadolinium Gallium Garnet (GGG, Gd 3 Ga 5 O 12) is a synthetic crystalline material of the garnet group, with good mechanical, thermal, and optical properties. It is typically colorless. It has a cubic lattice, a density of 7.08 g/cm 3 and its Mohs hardness is variously noted as 6.5 and 7.5. Its crystals are produced with the Czochralski method ...

  9. Gadobutrol - Wikipedia

    en.wikipedia.org/wiki/Gadobutrol

    Gadobutrol is a medicinal product used in diagnostic magnetic resonance imaging (MRI) in adults and children. It provides contrast enhancement during cranial, spinal, breast, or other investigations. In the central nervous system, Gadobutrol works by highlighting any areas with disrupted blood brain barrier (BBB) and/or abnormal vascularity.
