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 contrast agent being tested by researchers not only pinpoints breast cancers at early stages but differentiates between aggressive and slow-growing types. A new ...

At this year’s European Congress of Radiology (ECR) in Vienna, Bayer presented new data on a contrast agent that could ...

Photoacoustic imaging has gained global attention for capturing images without causing pains or using ionizing radiation. Recently, many researchers have heavily studied on observing deep tissues to ...

Experiments in dogs, rabbits and monkeys show the efficacy and biocompatibility of a new MRI/MRA contrast agent in detecting stroke. This T1 MRI contrast agent based on ultrasmall iron oxide ...

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 ...

MRI contrast agents, which are typically gadolinium-based, are used to enhance visualization of abnormal structures or lesions and to aid differentiation between healthy and pathological tissue. This ...

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 ...
