Hidden Hazards of MRIs
Gadolinium, a rare earth element used in contrast agents, may contribute to the potential hazards of MRIs.
One aspect of these scans is under scrutiny. About one third of MRIs involve injections of a contrast agent to make the resulting image clearer. Some contrast agents contain gadolinium, a rare earth chemical element. For years, scientists have been expressing caution about the safety of gadolinium. This rare ...
earth metal can sometimes linger in the body, and may cause systemic fibrosis, a serious complication. Researchers at the University of New Mexico have found that diet may help contribute to this problem (Magnetic Resonance Imaging, June, 2025). People who have been consuming foods rich in oxalates such as spinach, rhubarb, beets, nuts or chocolate seem to be more likely to form toxic metal nanoparticles.
