Late gadolinium enhancement (LGE) and T1 mapping allow infarction and fibrosis to be identified for characterizing cardiomyopathy and assessing viability. [8] Magnetic resonance angiography may be performed with or without contrast medium and is used to assess congenital or acquired abnormalities of the coronary arteries and great vessels. [9]
In the second and third trimester, gadolinium contrast is associated with a slightly increased risk of stillbirth or neonatal death, by the same study. [45] Guidelines from the Canadian Association of Radiologists [46] are that dialysis patients should receive gadolinium agents only where essential and that they should receive dialysis after ...
Delayed Gadolinium-enhanced MR Imaging of Articular Cartilage: Three-dimensional T1 Mapping with Variable Flip Angles and B1 Correction; Toward Imaging Biomarkers for Glycosaminoglycans; Longitudinal Evaluation of Cartilage Composition of Matrix-Associated Autologous Chondrocyte Transplants with 3-T Delayed Gadolinium-Enhanced MRI of Cartilage
The Lake Louise Criteria include increased signal intensity after gadolinium contrast enhancement (a sign of hyperemia, or increased blood flow to damaged tissue), increased myocardial T2 relaxation time or an increased T2 signal intensity (which are signs of tissue edema or swelling), and late gadolinium contrast enhancement (which is a sign ...
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.
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".
Gadopiclenol was approved for medical use in the United States in September 2022 by the Food and Drug Administration. [2] [12]In October 2023, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Elucirem, intended for contrast-enhanced ...
