Although contrast agents have an essential role in non-invasive imaging techniques, potential side effects limit their use. For example, both low- and iso-osmolar iodinated contrast media used in ...

A new magnetic resonance imaging (MRI) contrast agent being tested by researchers at Case Western Reserve University not only pinpoints breast cancers at early stages but differentiates between ...

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 ...

Magnetic resonance imaging (MRI) visualizes internal body structures, often with the help of contrast agents to enhance sensitivity. Scientists have now developed a bimodal contrast agent suited for ...

In a possible first, researchers at Stanford (Calif.) Medicine found a non-invasive imaging method to visualize senescent cells. “As we age, we accumulate senescent cells. These are like ‘zombie cells ...

Scientists at the Institute of Chemistry have developed a new type of contrast agent for magnetic resonance imaging (MRI)—bovine serum albumin nanoparticles doped with manganese (II) ions. The results ...

Compared to group I GBCAs, group II GBCAs appear safe for use in patients with severe kidney disease. In a recent analysis, the risk of NSF in patients with stage 4 or 5 CKD was less than 0.07% with ...

One of the most widely used drugs in the world isn't really a drug, at least not in the usual sense. It's more like a dye. Physicians call this drug "contrast," shorthand for contrast agent. Contrast ...

Researchers have found that patients with family and personal history of allergic reactions to contrast media are at risk for future reactions, according to a new large study. Allergic reactions to ...
