  2. 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/Contrast_agent

    A contrast agent(or contrast medium) is a substanceused to increase the contrastof structures or fluids within the body in medical imaging.[1] Contrast agents absorb or alter external electromagnetismor ultrasound, which is different from radiopharmaceuticals, which emit radiationthemselves. In X-rayimaging, contrast agents enhance the ...

    en.wikipedia.org/wiki/Gadopiclenol

    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.

  6. Radiocontrast agent - Wikipedia

    en.wikipedia.org/wiki/Radiocontrast_agent

    Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.

    en.wikipedia.org/wiki/Magnetic_resonance_imaging

    003335. 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. MRI does not involve X-rays or the use of ...

  8. 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 ...

  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".
