OBJECTIVE To prevent iodinated contrast medium-induced nephrotoxicity, gadolinium has been used increasingly for magnetic resonance angiography (MRA) or conventional digital subtraction angiography (DSA) to visualize arterial anatomy in patients undergoing vascular surgery who are considered at high risk because of chronic renal insufficiency. We assessed the safety of gadolinium-based contrast...
Background Patients with hereditary tumor syndromes undergo periodical magnetic resonance imaging (MRI) screening with Gadolinium contrast. Gadolinium accumulation has recently been described in the central nervous system after repeated administrations. The prevalence and rate of accumulation in different subgroups of patients are unknown. Neither are the mechanism nor clinical impact. This may...
Abstract This paper reports the development and detailed properties of about 13 metric tons gadolinium sulfate octahydrate, $\rm Gd_2(\rm SO_4)_3\cdot \rm 8H_2O$, which has been dissolved into Super-Kamiokande (SK) in summer 2020. We evaluate impact radioactive impurities 8H_2O$ on diffuse supernova neutrino background searches solar observation confirm need to reduce fluorescent by three order...
Background Gadolinium-enhanced CMR can be a useful adjunct in the diagnosis and assessment of acute myocardial infarction (AMI). However, gadolinium contrast is contraindicated in severe renal impairment. Alternative, non-gadolinium contrast agents for AMI assessment and contrast-enhanced CMR in general would be of substantial clinical importance. Ferumoxytol, an intravenous iron-supplementatio...
Gravid macaques (n=12) were maintained on a control diet (14% calories from fat, n=4) or a high fat diet (36% calories from fat, n = 8). On gestational day 129, the macaques were injected with ProHance gadolinium contrast for placental imaging (equivalent to the third trimester). Gadolinium dose was varied based on maternal weight, using 0.1 mmol/kg dosing. Fetuses were delivered via cesarean s...
a o t I o c t Gadolinium-based extracellular contrast agents have enabled cardiac magnetic resonance (CMR) to assess viability and fibrosis at a higher resolution than alternative technologies (1). In this issue of iJACC, Matsumoto et al. (2), present convincing data that early contrast enhancement approximately 2 min after administration of gadolinium depicts the area at risk associated with a...
Since thermoelectrics are an important way to produce electricity from waste heat, the thermoelectric properties of gadolinium copper telluride, GdCuTe2, together with the doped compounds gadolinium samarium copper telluride, Gd1-xSmxCuTe2, and gadolinium dysprosium copper telluride, Gd1-xDyxCuTe2, with x = 0.02 and x = 0.05 were investigated. Upon doping, a decrease in thermal conductivity and...
