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 the T1 relaxation time (and to some extent the T2 and T2* relaxation times) in MRI, which is the source of its clinical utility. Because ...
The World Health Organization issued a restriction on use of several gadolinium contrast agents in November 2009 stating that "High-risk gadolinium-containing contrast agents (Optimark, Omniscan, Magnevist, Magnegita, and Gado-MRT ratiopharm) are contraindicated in patients with severe kidney problems, in patients who are scheduled for or have ...
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".
Meglumine is a sugar alcohol derived from glucose that contains an amino group modification. It is often used as an excipient in pharmaceuticals [ 1 ] and in conjunction with iodinated compounds in contrast media such as diatrizoate meglumine , iothalamate meglumine , and iodipamide meglumine .
Gadolinium gallium garnet (GGG, Gd 3 Ga 5 O 12) is a synthetic crystalline material of the garnet group, with good mechanical, thermal, and optical properties. It is typically colorless. It has a cubic lattice, a density of 7.08 g/cm 3 and its Mohs hardness is variously noted as 6.5 and 7.5.
The decahydrate of gadolinium oxalate thermally decomposes to obtain the anhydrous form, which can then be heated to produce gadolinium oxide. [2] Gadolinium oxalate reacts with hydrochloric acid to produce Gd(C 2 O 4)Cl. [3] It also reacts with sodium hydroxide under hydrothermal conditions to produce gadolinium hydroxide. [1]
It’s estimated that nearly 5% of Americans above the age of 12 live with hypothyroidism, a condition that occurs when the body experiences a deficit of thyroid hormone.. The thyroid gland ...
The chemical name of tafamidis is 2-(3,5-dichlorophenyl)-1,3-benzoxazole-6-carboxylic acid. The molecule has two crystalline forms and one amorphous form; it is manufactured in one of the possible crystalline forms. It is marketed as a meglumine salt. It is slightly soluble in water. [10]
