Nanoscientists have demonstrated a method for loading nanoparticles with iron ions to create MRI contrast agents that outperform gadolinium chelates, the mainstay contrast agent that is facing ...

Depending on the thermodynamic complex stability, addition of the trivalent metal salts may cause transmetallation or recomplexing in the MRI contrast agents, resulting in the release of toxic Gd 3+ ...

Magnetic resonance imaging (MRI) contrast agents have had a significant impact on the value of MRI by enhancing the visibility of internal bodily structures such as organs and vasculature. MRI ...

Qualitative ratings showed non-significant differences between the proposed method – a 10% level of gadolinium dose – and acquired full-dose contrast-enhanced MRI images, which was also verified with ...

CAMBRIDGE, MA -- To enhance the visibility of organs as they are scanned with magnetic resonance imaging (MRI), patients are usually injected with a compound known as a contrast agent before going ...

OAK BROOK, Ill. - Brain MRI without contrast agent is just as effective as the contrast-enhanced approach for monitoring disease progression in patients with multiple sclerosis (MS), according to a ...

Expecting mothers who undergo an MRI in their first trimester shouldn’t have much to worry about if it was a standard one, according to a recent study of more than 1.4 million women. But an MRI that ...

Gadolinium-based contrast agents (GBCAs) used in MRI and angiography contain a chelated form of the toxic heavy metal that was assumed to clear the body shortly after intravenous administration. [1] ...

Contrast materials can help highlight areas of interest in MRI scans. Contrast injections may cause side effects like mild rashes and hives, but, in rare instances, it is also possible for a person to ...
