FYI if you're getting a contrast MRI in the near future, avoid vitamin c. https://hscnews.unm.edu/news/unm-scientists-discover-how-nan...




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.

Same here, also in Sweden.

see sections “Why Would I Need a Contrast MRI?” and “Which Types of MRI Require Contrast”

> 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?

I’m a New Zealand MR tech. Based on the practice of my European colleagues, they give it just as often as we do.


I'm in the UK and getting one to diagnose ED/recurrent priapism.

I have one planned soon. Of course the prescribing doctor didn't mention any of this, but I guess the research is still too fresh. Thanks for raising awareness.

Many variants seem to be banned in Europe [1]

Getting one on Monday, have a slight cold and took liposomal vitamin c just hours ago!

Thanks for making me aware!


*If your scan involves contrast agent, which many do not

My late grandfather had a severe reaction to contrast agent while getting an MRI and coded while in the machine. (They resuscitated him)

thanks

I thought I read that in general it’s just better to decline contrast because it doesn’t actually add value to the scan.

It depends on the indication for the scan. Some indications do not require contrast, others MUST have contrast in order to have any value. If you refuse contrast without understanding the reason, you may be simply wasting your time and money.
