    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".

    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).

    The 50% lethal dose is about 0.34 mmol/kg (IV, mouse) [52] or 100–200 mg/kg. Toxicity studies in rodents show that chelation of gadolinium (which also improves its solubility) decreases its toxicity with regard to the free ion by a factor of 31 (i.e., the lethal dose for the Gd-chelate increases by 31 times).

    Studies using MRI showed that liraglutide (Victoza), a GLP-1 agonist used for diabetes, and tirzepatide (Zepbound) led to muscle loss that was expected with the observed magnitude of weight loss ...

  9. Diffusion-weighted magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Diffusion-weighted...

    When water is in an environment where it can freely tumble, relaxation tends to take longer. In certain clinical situations, this can generate contrast between an area of pathology and the surrounding healthy tissue. To sensitize MRI images to diffusion, the magnetic field strength (B1) is varied linearly by a pulsed field gradient.
