Re: Why Metal Objects Are Forbidden In An MRI Suite
Yes, many hospitals lately have replaced their floors with grass, which is kept in pristeen condition with lawn mowers. Indeed, in the British Golf Open last year, the MRI suite at St. Andrew's Infirmary was used as the green on the 18th hole.

Re: Why Metal Objects Are Forbidden In An MRI Suite
It depends on what the metal really is in your arm.. I have titanium implants in my left leg, though these were referred to as steel plates by some of the medical staff at the time of my operation. In times gone by most procedures did use stainless steel implants and fixations, and the term "steel," is often used as a generalization in reference to the fact that the implants are metal. It is also easier to say "steel," than it is to say "non-ferrous titanium alloy,". So if your procedure was done in recent times it is probable that you have a non magnetic alloy implant. If it is indeed stainless steel or other magnetic material, then the MRI scanner can run with a lower field intensity, around 1.5 Tesla, and your implants will remain undisturbed. The MRI scanner will not rip a hole in your arm. The worst metal to have in you are things like metal splinters, if you work on any kind of metal machinery, such as a lathe, or welding equipment it is important that you mention this before a scan. You don't want a metal splinter to get sucked backwards into your eyeball, that could really ruin your day.

Re: Why Metal Objects Are Forbidden In An MRI Suite
Nice to know that. A couple of years ago I was dumb enough to do some metalwork with a Dremel on something made out of steel. Dumb dumb that I was, I didn't wear any protective goggles, and ended up getting one or two little fragments of steel embedded into my eyeball. It was really uncomfortable and thus I ended up going to the GP, who then anesthetised my eyeball and once that stuff was working he went to town on my eyeball with a .... yeah you guessed it right, another Dremel! Well not literally, it was a surgical version, and a lot smaller, like one of those battery powered ones, but still. It was really weird because I could feel the pressure on my eyeball but no pain or anything, while he was grinding away at my eye to get that stuff out. Anyways, I have no idea if he got all of it, good chance there is still some left in my eyeball, and I can imagine the end result won't be pretty if I ever end up going through an MRI. So thanks for reminding me about that fact again |
