Oxalic acid may cause bad reactions to MRI dye

Scientists have potentially identified a link between oxalic acid and adverse reactions to MRI contrast dye, which could explain why some patients become ill after scans. Researchers found that oxalic acid, present in foods and supplements, may bind with gadolinium, the metal used in the dye, causing it to leach out and potentially infiltrate cells, leading to internal organ damage. This could explain the varying reactions to the dye. This discovery could lead to recommendations, such as avoiding Vitamin C supplements before MRIs, to minimize adverse effects like systemic fibrosis, a severe condition linked to gadolinium buildup.
