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]
Nephrogenic systemic fibrosis is a rare syndrome that involves fibrosis of the skin, joints, eyes, and internal organs. NSF is caused by exposure to gadolinium in gadolinium-based MRI contrast agents (GBCAs) in patients with impaired kidney function. [1][2] Epidemiological studies suggest that the incidence of NSF is unrelated to gender or ...
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 ...
Cardiac magnetic resonance imaging (cardiac MRI, CMR), also known as cardiovascular MRI, is a magnetic resonance imaging (MRI) technology used for non-invasive assessment of the function and structure of the cardiovascular system. [2] Conditions in which it is performed include congenital heart disease, cardiomyopathies and valvular heart ...
Gadolinium is a chemical element; it has symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is a malleable and ductile rare-earth element. Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating. Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic, with ...
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.
Nephrology, radiology. Contrast-induced nephropathy (CIN) is a purported form of kidney damage in which there has been recent exposure to medical imaging contrast material without another clear cause for the acute kidney injury. Despite extensive speculation, the actual occurrence of contrast-induced nephropathy has not been demonstrated in the ...
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. In X-ray imaging, contrast agents enhance the ...
