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 specially coated iron oxide nanoparticle could provide an alternative to conventional gadolinium-based contrast agents used for magnetic resonance imaging (MRI). In rare cases, the currently used ...

Patients who need repeated MRI scans with contrast dye could soon receive a fraction of the gadolinium they currently get.

(Phys.org)—A new type of nanoparticle-based MRI contrast agent demonstrates selectivity for tumor cells over non-cancerous cells, can detect hypoxia, and is sensitive enough allow for the detection of ...

A group of researchers led by Leif Schroeder from the Leibniz-Forschungsinstitut fuer Molekulare Pharmakologie (FMP) have found a way to detect metastases in certain types of cancer in the brain at an ...

NEW ORLEANS ― For patients with suspected coronary artery disease, the intravenous administration of a contrast agent during angiography is safer and faster than intra-arterial administration, a ...

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 into the scanner.

Skoltech researchers and their colleagues have synthesized and tested protein-polymer microbubbles for use in medical ultrasound imaging of internal organs. Administered intravenously, the ...

The FDA has approved Bayer’s Ambelvist (gadoquatrane), the lowest-dose macrocyclic GBCA for adult and pediatric contrast-enhanced CNS and body MRI exams.

Nephropathy induced by exposure to radiocontrast agents, a possible complication of percutaneous coronary interventions, is associated with significant in-hospital and long-term morbidity and ...

Researchers have taken a key step forward in developing a new, possibly safer contrast agent for use in MRI exams. Researchers at Massachusetts General Hospital (MGH) have taken a key step forward in ...
