  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. Contrast agent - Wikipedia

    en.wikipedia.org/wiki/Contrast_agent

    Gadolinium is used in magnetic resonance imaging as an MRI contrast agent or gadolinium-based contrast agent (GBCA). [3] In the 3+ oxidation state, the metal has seven unpaired electrons. This causes water around the contrast agent to relax quickly, enhancing the quality of the MRI scan.

  4. Gadopiclenol - Wikipedia

    en.wikipedia.org/wiki/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. [2]

  5. Gadolinium - Wikipedia

    en.wikipedia.org/wiki/Gadolinium

    Paramagnetic ions, such as gadolinium, increase nuclear spin relaxation rates, making gadolinium useful as a contrast agent for magnetic resonance imaging (MRI). Solutions of organic gadolinium complexes and gadolinium compounds are used as intravenous contrast agents to enhance images in medical and magnetic resonance angiography (MRA) procedures.

  6. 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).

  7. Gadodiamide - Wikipedia

    en.wikipedia.org/wiki/Gadodiamide

    A bottle of Omniscan contrast agent. 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 ...

  8. 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.

  9. Gadopentetic acid - Wikipedia

    en.wikipedia.org/wiki/Gadopentetic_acid

    Gadopentetic acid, sold under the brand name Magnevist, is a gadolinium-based MRI contrast agent. [2]It is usually administered as a salt of a complex of gadolinium with DTPA (diethylenetriaminepentacetate) with the chemical formula A 2 [Gd(DTPA)(H 2 O)]; when cation A is the protonated form of the amino sugar meglumine the salt goes under the name "gadopentetate dimeglumine".
