Ya get one "know-it-all" type coming in, and after that all hell breaks loose b/c they can't stand to be challenged, even though everyone is anonymous.
Actually it was a couple of know it alls that were just looking for a fight. That is why they kept changing the subject title, because they did not want to address the topic, they just wanted to fight. That is why I stopped responding to their crap.
As for the MRI, my guess is that nobody can know whether they're "safe" or not. It is un-natural to subject the body to such strong magnetic fields, and there is magnetite in the pineal gland and other body compartments - one can only conjecture whether there's a long term effect of aligning these magnetic domains, but since the body never reaches the Curie temperature of iron, my guess is that the effect would be long-term.
You missed part of the point. The original poster did not say what the scan was for. It could be something potentially serious. And if it is then many serious issues cannot be diagnosed without looking directly at the problem. In other words it is likely to require either some form of scan or surgery. The scans are safer and less invasive. And without looking at the problem what are the risks? Permanent injury? Death?
So your question might be re-worded as "Is it safe to align the magnetic domains of all the magnetite in my body ?"
I don't know the answer, other than, if these domains are aligned via MRI, then they would afterwards remain in such an aligned state for a while, which I view as not natural.
Surgery is not natural either, but it may be the only other option. But as I pointed out in my original post the role of the MRI magnet is to align the protons TEMPORARILY. It is not long term at all.
If I had a choice between an MRI or surgery though I will go with the MRI in a heartbeat.
And for anyone with an ego trip who reads this and wants to reply negatively to my opinion, which I claim to be neither right nor wrong, let me say in advance that you all can kiss my @$$.
No thanks. I do not kiss donkeys or anything as hairy as one.
