Another controversial issue regarding the use of gadolinium
is its effect on renal function and induced nephropathy.
There were no significant discrepancies between reviewers' final decisions, and they agreed with full consensus regarding the presence or absence of leptomeningeal enhancement or superiority of FLAIR or T1 with gadolinium
enhancement to detect leptomeningeal disease.
We therefore aimed to determine three things regarding this phenomenon: (a) the effect of different gadolinium
preparations on calcium values; (b) the magnitude of this effect in three different calcium measurement methods; and (c) to what extent impaired glomerular filtration rate (GFR) would lengthen the time that these agents would adversely affect calcium values.
It consists of a wheel that contains segments of gadolinium
powder and a high-powered, rare earth permanent magnet.
at post-injection acquisition times of 3-10 minutes as typically performed for brain tumor imaging) depends solely on the total amount of gadolinium
in the lesion (i.

The FDA required manufacturers of five gadolinium
contrast agents to strengthen boxed warnings on their products to minimize the risk of nephrogenic systemic fibrosis in some patients with kidney dysfunction.
(Gd) is the material most commonly used as an MRI contrast agent, but its contrast efficacy can be improved.
First, the form of the gadolinium
(whether part of a Gd-ligand complex or in some other form) is unknown.
However, Simon Robinson of Lantheus Medical Imaging in North Billerica, Massachusetts, and his colleagues found a way around this using gadolinium
chelate, a substance that is already used to light up blood in MRI scans.
Considered extremely safe for most patients, gadolinium
contrast has been linked to development of nephrogenic systemic fibrosis in about 200 patients with renal disease.
Diffuse meningeal enhancement on MRI with gadolinium
contrast can confirm the diagnosis of intracranial hypotension when a patient presents with orthostatic headaches, said Todd J.
Dodgers closer Eric Gagne will undergo a second MRI involving a more revealing gadolinium
dye on his ailing right elbow Tuesday in Los Angeles.
During that time, tumor gadolinium
uptake and washout rates are assessed to generate morphophysiologic maps of the malignancy, that are converted into predicted treatment response scores.
