  2. 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.

  3. MRI contrast agent - Wikipedia

    en.wikipedia.org/wiki/MRI_contrast_agent

    A contrast agent usually shortens, but in some instances increases, the value of T1 of nearby water protons thereby altering the contrast in the image. Most clinically used MRI contrast agents work by shortening the T1 relaxation time of protons inside tissues via interactions with the nearby contrast agent.

    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).

    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".

    Heating non-ionic contrast agent to human body temperature reduces its viscosity. [2] The amount of iodine administered in children in the United States in 2010 was 272 to 740 mg/kg for CT scan. [3] Iodine contrast agents are used for the following: [citation needed] Contrast CTs; Angiography (arterial investigations) Venography (venous ...

    It does not need gadolinium contrast. [23] Dynamic contrast enhanced: DCE: Measures changes over time in the shortening of the spin–lattice relaxation (T1) induced by a gadolinium contrast bolus. [24] Faster Gd contrast uptake along with other features is suggestive of malignancy (pictured). [25] Functional MRI (fMRI) Blood-oxygen-level ...

  9. Contrast agent - Wikipedia

    en.wikipedia.org/wiki/Contrast_agent

    A contrast agent (or contrast medium) is a substance used to increase the contrast of structures or fluids within the body in medical imaging. [1] Contrast agents absorb or alter external electromagnetism or ultrasound , which is different from radiopharmaceuticals , which emit radiation themselves.
