Might render Gadolinium contrast.
These are ferromagnets(cobalt, nickel with iron, Gadolinium, and also compounds and alloys of these metals).
Gadolinium is used in as many as 45% of MRI exams in the United States.
His team pointed to several ways
imaging centers could prevent inadvertent Gadolinium exposure in pregnant women.
They also concluded that further studies should examine whether or
not Gadolinium leakage occurs in healthy individuals.
Instead, survivors could be given a
substance that collects in the eyes in the same way that Gadolinium does.
At the 2-hour scan, Gadolinium was mostly present in the aqueous chamber,
which is at the front of the eye.
The FDA has advised all MRI centers to provide a medication
guide to outpatients the first time they receive Gadolinium.
The NIH researchers discovered
that a stroke can also disrupt the blood-ocular barrier and allow Gadolinium to leak into the eye.
Named after the small town of Ytterby near Stockholm in Sweden. Terbium.
Ytterbium and Gadolinium are also named after this town.
The researchers found no link between the extent of Gadolinium leakage and the amount of disability that participants experienced after their strokes.
The team observed Gadolinium leakage in both the people who received a clot-busting treatment
known as tissue plasminogen activator and those who did not.
For their study, the scientists compared hospital MRI scans of 167 stroke survivors that
were done before and after they were injected with Gadolinium.
The participants who showed Gadolinium present in the vitreous chamber at the 24-hour scan
tended to be older and had a history of high blood pressure.
But a stroke can damage the tiny blood vessels and cause leakage in the blood-brain barrier,
which allows some Gadolinium to leak into the brain tissue.
The results showed that Gadolinium had leaked into the eyes of 66 percent
of stroke survivors at the 2-hour scan and 75 percent at the 24-hour scan.
In this study, data on nearly 4.7 million live births in the United States between 2006 and
2017 found that Gadolinium exposure occurred in one in 860 of those pregnancies.
Often, this involves having an injection of a contrast agent called Gadolinium, which is a harmless substance that travels to the brain
and lights up any abnormal areas on the scan.
The minority of individuals who had Gadolinium in both eye chambers at the 2-hour scan were
mainly those whose strokes had affected a larger area of the brain and had impaired more of the blood-brain barrier.
The second theory, which is not well accepted, proposed that the burning reactor released certain rare earth elements,
like samarium, Gadolinium and dysprosium, which absorbed the neutrons and stopped the chain reaction,
for a time, or in certain places, only to have it pop up again nearby.
