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 ...

(Reuters Health) - In the critical first trimester of pregnancy, undergoing magnetic resonance imaging (MRI) without a contrast agent is not associated with any negative outcomes for the baby, ...

Contrast media used for medical imaging may be contributing to environmental pollution as researchers measure and consider the impact.

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 ...

Nanoscientists have demonstrated a method for loading nanoparticles with iron ions to create MRI contrast agents that outperform gadolinium chelates, the mainstay contrast agent that is facing ...

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 ...
