Are MRI's Dangerous?

post #1 of 8
Thread Starter 
I'm scheduled to have my third one within 6 years. The first was in 10/03 when I had meningitis. The second was within a year because I thought I had meningitis again (turns out it was an ocular migraine, but still had white cells in my spinal fluid?? Residual maybe?)

Now, we are trying to figure out what it affecting my central nervous system, Lyme, MS, something is making my eye bulge & causing my vision to deteriorate, along with neuropathy & achey joints.

I feel like the MRI is needed to rule things out or diagnose, how bad ar they?

From what I can tell, there is no hard data showing that MRIs are bad for you, but there's some theoretical scientific discussion devoted to hypothetical problems and appropriate exposure limits for patients and technicians.

If you have the energy to read through the technical discussion, I found this page pretty informative about possible adverse effects. It's focused on exposure limits but goes through the various issues one by one.

I would feel a lot better about an MRI than (say) a CT scan or a bunch of x-rays.

Now that you mention it....maybe those two procedures I had *were* CT's....hmmm, how do you tell the difference? I went in a tube, not for very long & had to lie still.

An MRI has you completely surrounded (you're entirely in the tube), and a CT scan looks like a big doughnut that you go "through," but you're not entirely "in." Make sense?

Also, MRI is VERY NOISY. Not all the time but when it iakes pictures.

No, they are not dangerous, as far as I know, but I will say that my energy felt quite a bit "off" and I felt a little shaky after mine. Took a few hours to feel centered again. (hardly a danger, just thought it was interesting - it surprised me)

I think any danger that may be inflicted by an MRI is far far far outweighed by being able to diagnose and cure the disease. I hope you're feeling better and that they can get to the bottom of what is ailing you.
