A new study suggests that a chemical used in MRI scans may cause deadly nanoparticles to form in the body. Researchers from the University of New Mexico found that gadolinium, a toxic rare earth metal, can mix with oxalic acid found in many foods to create these tiny particles.
The study warns that patients taking certain supplements before an MRI scan may be at risk. Gadolinium-based contrast agents are commonly used to create sharper images during scans. However, even if no adverse effects occur, the metal particles have been detected in kidney and brain tissues, and have been found in the blood and urine years after exposure.
The researchers believe that oxalic acid, found in foods like tomatoes and spinach, plays a key role in the formation of these nanoparticles. They suggest that some people may be more susceptible to this process due to their metabolism.
To mitigate risks associated with MRI scans, scientists recommend avoiding vitamin C supplements before undergoing an MRI scan. The study aims to provide recommendations for helping individuals at risk of developing potentially deadly health problems.
