check the data on the mri... it should be NO METAL... even if put here surgically, the magnets are so strong they can rip it out... ever see that house episode where the plate came out of the girls skull in the mri? or how about the story about the O2 tank going flyin b/c a stupid tech left it in the wheelchair.... dead patient!! O2 projectile!
Ok, I'm going to try my best to not be a jackass here... but...
*You really should check your facts before posting something liek this*.
First of all, 90% of what you see on house is COMPLETE BS.
My wife has now heard me scream at the TV so many times watching thsi show that she now pre-empts what I'm going to compi nabout before I can get it out of my mouth. They have NEVER had a scene with an MRI that was any where close to accurate. On the same episode where they have that plate rip out, tehy also have people runnin in/out of the room wearing all kinds of metal objects, clipboards, etc. Gee, wonder why that would be a bad idea? If that plate is dangerous, then so is an ferrous metal object.
You can't "turn on" and MRI magnet. The magnetic field is ALWAYS on. The only thing that changes is an RF gradient going between 2 or more fields. So when they slide somebody in there, and everything is OK until they flip a switch - Bullshit. Oh yeah and how they show then looking at image while they're bein gacquired? More bullshit. You have to at least wait until it's done completing the sequence before you can see it.
Ok I'll have to quit on House now before I get into a real tyrade.
... even if put here surgically, the magnets are so strong they can rip it out...
INCORRECT sir.
99% of surgically implanted objects these days are made of titanium (non-ferrous) or stainless steal (very weakly magnetic). Things do NOT get ripped out of your body. Biggest problem is that they can get warm or a little uncomfortable.
We scan people w/ pins, rods, screws, all kinds of crap in them all the time. Why? Well, first of all you don't put that part in the center of the bore, where the field is strongest - b/c if you try to image the part where the object is, it creates such a big artifact the image is worthless anyway.
Second of all, body tissue is a lot stronger than you'd think. It holds things in place pretty well. Strong enough to not let it get ripped out like that.
Look at the distribution of magnetic field strength line ("Gause lines") from the center, you'll see the strength falls off at a fast non-linear rate.
Simple fact, having an implant does NOT necessarily disqualify you.
Now, we don't scan folks w/ anything close to their heart, blood-flow related, or otherwise critical for life, just in case something were to happen. And for research studies, we are even more picky just because we can be.
The case you speak of, o2 tank, is indeed real. Yes, it becoems a projectile. In a few minutes I'll link some crazy videos that show how strong it is. However one shoudl note that the tank was not bolted down. Had it been properly secured (Note it should *not* have been brought nearby anyway) that accident would have been prevented.
Because of the strength of the field and the portenial dangers, we are all very, very very cautious. At our facility, we don't even allow staff in the room OUTSIDE the scanner room unless they (a) have been safety trained AND certified, or (b) are specifically with somebody else who IS... and that person is held liable for their actions. Tragic accidents like above are very, very rare - but of ocurse it only takes a few to set the standard.
None whatso
