not only vitamin c but fruits containing oxalic acid if I read that right. But I'm far more interested in when such contrast agents are warranted, because I'm not aware that in Europe that contrast agent would be used that much for MRI
For your anecdata I'm in Sweden and definitely had a contrast agent (presumably gadolinium based) for a recent MRI of my gallbladder/pancreas/liver area.
> previous research has shown that even in those with no symptoms, gadolinium particles have been found in the kidney and the brain and can be detected in the blood and urine years after exposure
So do you stop eating high oxilate and high vitamin C food for a year after the MRI? Are there foods or drinks that help flush gadolinium?
