  2. MRI contrast agent - Wikipedia

    en.wikipedia.org/wiki/MRI_contrast_agent

    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]

  3. 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.

  4. 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 ...

  5. Gadoteric acid - Wikipedia

    en.wikipedia.org/wiki/Gadoteric_acid

    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 ...

  6. Gadolinium(III) oxide - Wikipedia

    en.wikipedia.org/wiki/Gadolinium(III)_oxide

    Nanoparticles of gadolinium oxide is a potential contrast agent for magnetic resonance imaging (MRI). A dextran-coated preparation of 20–40 nm sized gadolinium oxide particles had a relaxivity of 4.8 s −1 mM −1 per gadolinium ion at 7.05 T (an unusually high field compared to the clinically used MRI scanners which mostly range from 0.5 to ...

  7. Gadodiamide - Wikipedia

    en.wikipedia.org/wiki/Gadodiamide

    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).

  8. Cardiac magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Cardiac_magnetic_resonance...

    Cardiac magnetic resonance imaging (cardiac MRI, CMR), also known as cardiovascular MRI, is a magnetic resonance imaging (MRI) technology used for non-invasive assessment of the function and structure of the cardiovascular system. [2] Conditions in which it is performed include congenital heart disease, cardiomyopathies and valvular heart ...
