Contrast agents

Many procedures in diagnostic imaging would be impossible without contrast agents: they open up insights into vascular structures, show stenoses, inflammations, aneurysms and more. However, reports about side effects – especially with gadolinium-based contrast media – cause uncertainty among many patients.

New MRI contrast agent to improve upon gadolinium-based products

Magnetic resonance imaging (MRI) is widely used to identify the narrowing or blockage of blood vessels. Contrast agents improve the visibility of the structures and offer more accurate information of vascular conditions such as vascular blockage and stenosis. Commonly used gadolinium-based contrast agents must be administered in chelated forms due to the gadolinium ions' high toxicity and pose…

Should Gadolinium-based contrast agents be used in breast DTI?

The accuracy of breast cancer diagnosis via diffusion-tensor imaging (DTI) was equivalent both before and after the administration of a gadolinium-based contrast agent (GBCA), despite a value change in DTI parameters, finds a new research article. “However,” wrote first author Anabel M. Scaranelo of Princess Margaret Cancer Centre’s breast imaging division in Toronto, “the limitations in…

Gadolinium in MRI is here to stay (at least for a while)

Manganese and iron oxide contrast agents can replace gadolinium-based contrast agents (GBCA) in a number of MRI examinations, but gadolinium remains a strong candidate when properly indicated, especially with AI-driven dose reduction and advances to increase relaxivity, a French expert explained at ECR 2020. GBCA have been MRI companions for many years. In France, 30% of all MR examinations are…
