Experts have provided new guidance in the use of contrast agents during MRI scans. Emerging research suggests gadolinium-based contrast agents, injected in a patient's veins to brighten tissues in MRI ...

To produce sharper images of organs through magnetic resonance imaging, doctors and researchers often inject patients with so-called contrast agents. The most commonly used agents contain the metal ...

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+ ...

Adding a contrast-enhancing agent to magnetic resonance imaging (MRI) significantly improves image quality and allows radiologists who interpret MRI scans to pick up subtle anatomic details and ...

The FDA has started a review of a novel MRI contrast agent developed by Bayer that can reduce levels of gadolinium, a rare earth metal that can have damaging health and environmental consequences.

Exploring MRI contrasts NIST researcher Samuel Oberdick and colleagues tested iron oxide nanoparticles at low-strength magnetic fields. Nanoparticles inside a liquid solution (pictured here) are ...

People with a history of allergic-like reactions to iodinated contrast media, which is used in a variety of X-ray-based procedures, such as CT and angiography, are susceptible to similar reactions ...

A medical innovation that has significantly advanced medical treatments, magnetic resonance imaging has helped doctors see inside the body. MRI scans are a non-invasive and relatively safe procedure.

Researchers are sounding the alarm about a dangerous interaction between oxalic acid and MRI contrast agents. This common compound found in many foods could promote the toxic buildup of gadolinium in ...
