His team pointed to several ways imaging centers could prevent inadvertent gadolinium
exposure in pregnant women.
"While there is clear evidence that all types of [gadolinium contrast agents], both linear and macrocyclic, may result in trace amounts of gadolinium
in the brain, there exists no clinical evidence that this leads to an increase in risk or harm to patients," a press release from GE Healthcare defended the company's MRI contrast agent Omniscan; and continued stating that "Omniscan has a specific cardiac indication in several European Member States; removing it would limit clinical choice."
Dr Walsh claims gadolinium
contrast agents should not have been granted licences without more research.
Omniscan possesses a linear molecular structure, which is less stable and has greater gadolinium

We measured the signal intensity of each cell pallets to obtain quantitative data, which is also an indirect method to determine the gadolinium
deposition in the cells.
Most of the patterns (excluding those for the samples with gadolinium
doping of 2.5 and 4.3 mol.%) contain the same sequence of the reflections at 2[theta] = 30.2, 35.5, 43.2, 53.5, 57.2, and 62.7[degrees] indicative for an inverse spinel phase and corresponding to (220), (311), (400), (422), (511), and (440) crystallographic planes, respectively, which is immanent to both magnetite and maghemite .
 have used all these performance indicators to numerically determine the cooling and overall performance of a micro-channel AMR magnetic refrigerator using gadolinium
and water as MCM and heat transfer fluid respectively.
The consensual use of the 3 criteria "Lake Louise Criteria" (signal intensity increase in T2-weighted images "edema," early gadolinium
enhancement in T1-weighted images "hyperemia," and late gadolinium
enhancement in T1-weighted images "necrosis and fibrosis") has standardized the CMR protocol for myocarditis diagnosis .

oxysulfide nanophosphors ([Gd.sub.2][O.sub.2]S-NPs) were chosen due to its high chemical and thermal stability as well as wide band gap energy in the range of 4.6 to 4.8 eV, which is suitable for ionic doped activation  and efficiently reacted to become as a luminescent emitting material .
A contrast-enhancing agent, such as gadolinium
, is injected into a vein in the arm.
