@TheCrazy243 your screws should be very safe. Generally after a month or so after having surgery with implanted metal, it's safe to have an MRI. The exceptions to this would be if you had a pacemaker, or an aneurysm clip in your brain.
And you'd be unlikely to have an MRI of the knee anyway. The presence of metal around the bit that is scanned causes a lot of artefact and parts of the image aren't there.

@cronnin iys a magnet, it still works when its off, if he gets close enough, it will f*** up his phone, credit card, iPod, compass, YMCA card anything pretty much, dont wear steet toe boot neaf one and lift a foot, (personal experince) you will get stuck..
Please answer my question: Why do my compass respond to Earth's magnetic field, but won't budge when I'm in a hospital with an MRI? Does that imply the Earth's magnet is stronger?
@TheKuroky the rooms where MRIs are conducted are surrounded by shielding in the walls to prevent the MRI from reacting to things outside of the room, usually there is a little computer where the results of the scan are sent and the operator can see them, if there was no shielding, the computer outside of the room would not function, among other devices in the vicinity of the MRI room
@Ant1matt3r Ummm, not quite. All clinical MRI's are in rooms that have radiofrequency (RF) shielding. Not all of them (in fact, a minority) have magnetic shielding (a completely separate system). The RF shield generally does nothing with respect to keeping the magnetism inside the room. This is fundamentally different than every other type of shielding used in radiology.
@MarbleMagic Neither are the plates, pins and screws doctors use to mend broken bones but they still cause a big problem in MRI machines.
The magnet in an MRI is strong enough to super heat any metal (even a 1.5T one, which is actually fairly wimpy by today's standards). The heating causes severe burns, it's nothing to do with metal being pulled out of your body, unless you're unfortunate enough to have some sort of iron in you - some bullets contain iron for example.
I never had problems with implants heating up, all they ever did was causing interferences in the images.
One patient we had in our 3T machine had a piece of shrapnel stuck in his forehead, from the accident he had - this nearly erased the whole picture. Other than that, nothing happened.
We also experience the same artifacts metal causes to appear with clothes made of synthetics. Not at 1.5T but at 3T and up.
i'll ask him again tommorow (well today, its 5am...) what I remember him saying is they put a dye in his blood and sent it backwards to see what muscles/ligaments we're abnormal.
don't always trust the net you know, I said to an x-ray doctor that x-rays are gamma because of wiki and he was adamant that x-ray is its own type, and he's the doctor, not that I feel I can trust most people nowadays but you catch my drift.
I don't know about that but there is a big section of radiology called Nuclear Medicine where they specialize in having a person drink or inject a radioactive isotope and they they can monitor it through live xrays as it passes through the body such a blood and tissue. I don't know if they do that with MRI's though.
@vampov thats pretty much it, he told me -the doctors- said the "dye" flows backwards and shows any irregularitys, which is what i've been trying to say. I'm no medic but I have heard of this before, one person I know had iodine injected in small amounts for a similar test for different reasons. i'm not sure I trust the knowledge of these exams, injecting you with radioactive material is quite frankly stupid from the average persons perspective of things and imo rightly so.
i think ur a little confused...dyes aren't injected for MRIs, ur thinking of CT scans. also, the amount of iodine that is put into the patient's blood stream is not near enough to harm them unless, of course, they are allergic to iodine. also, chemotherapy is radioactive and it helps treat cancer, so i don't think its stupid. its quite logical, but i guess if you don't know the facts it would make you wonder
@pointeprincess302 MRIs used non-iodinated contrast if the study calls for it. Also, the contrast used in CTs can absolutely be harmful. It is absolutely contraindicated in patients taking certain drugs as well as in patients with renal failure of certain severity.
@KKinsane2009 It depends on what definition one uses - there's some overlap in terms of energy; you can't say the doc was wrong for distinguishing the two.
I say again, my mums boyfriend HAD THIS DONE, so don't tell me its not possible else what were they actually doing to him and why did they lie in the explaination thereof??? common sense doesn't exist its a metaphor for well known knowledge, and I don't think people do know much to be honest.
Either way, even if it was possible for blood to oppose it's natural direction, the blood would have to had to stop at one point before it would even have a chance to reverse it's flow.....
very good point :) it is possible if you think about it, blood carries iron amongst other magnetic minerals through the body so its not like it can't be done, I guess i'm probably wrong but i'm just saying what the qualified mri user told the patient in question.
could be an awful like, saw (the films), machine if abused imo.
also ---> I would compare the overall magnetic feild size against tesla rating ratio and see which is stronger when the feilds are matched sizes.
It does not make your blood flow backwards. They can see blood flow by using an MRI contrast agent which is injected prior, or during the examination. Also MRI images offer an incrediable amount of detail.
dude i fucking hate MRI scanners i have 3 pins in my right leg with 6 screws and when ever i get one it feels like something tugging on it from the inside plus they are loud as shit
OW!!! STOP! you are making my leg hurt thinking about that!!! LOL! I have a rod in my leg from when I snapped my shin bone in two. I need to get it out soon as it is really starting to bother me (expecially in the cold). I have not had an MRI though, not since the breaking of my leg at least. I had a CT scan but thats a whole different thing. Man now if they send me to get an MRI anytime soon Im gonna freak out! My leg bothers me enough without magnets tearing it apart from the inside! LOL!

A quick google search on MRI accidents shows what happens when someone brings an office chair too close or some patients oxygen tank. It turns into a missile and cracks the plastic shell around the MRI machine.
MRI magnets are so powerful, they literally make every atom in your body vibrate and give off Radio Frequency waves. I really dont think its safe to expose your body to something that makes every atom in your body emit radio frequency. We will see in 20 or 50 years the long term effects.
The magnetic field does not make every atom in your body vibrate. It moves the magnetic field associated with the hydrogen protons. So....nothing is physically moving in your body. Your point about long-term effects may be right, but not remotely for the reasons you state.
... A magnetic field cannot cause vibration or resonance, it can only force protons to line up in one of two configurations... This doesn't cause the release EMR... You need to actually input EMR at the right frequency, to make a proton flip states... Look up NMR, same principle.
Please KNOW what you're talking about before you post something.
that is true. to actually be able to manipulate the metal using magnetic force. the metal should have good magnetic properties and not a lot of metals have that, mostly its rare earth metals that have those properties and even then they are quite weak.
There's a neurovascular surgical tool that uses a pair of big electromagnets (on either side of your head) to help 'steer' a catheter through the blood vessels in your brain to deploy a stent or clip at the appropriate place.
I've heard of strang effects that people experiene when around such high magnetic fields. I've had an MRI, and din't notice much with it, but has anyone ever seen The Philadelphia Experiment? It was the moovie about time travel, and all of those generators were in use then. I've also heard of other effect that people have experienced in high voltage environments like this.
DO you know what the "pumping" noise in the background, when i had one in sunderland royal hospital's new scanner, i think it was 2 tesla, all i could hear was that when i was stepping into the machine!
I don't know, but I heard a lot of clunking noise in mine in 1994! Not sure of what the strength of it was, at St. Johns Hospital in Detroit. I've heard people have noticed different effects when in an MRI that I've heard about over the years on Coast to Coast AM.
Liquid helium recondensing, aka the coldhead, liquid helium is not actually being made colder, but when the helium tries to expand into gas the coldhead recondenses it into liquid so it does not boil off.
I fix MRI machines, the pumping noise is the coldhead of the magnet, basically the way that this magnet is a magnet, is by running current trough it, the current once in the magnet remains in there, in order for it not to dissipate it needs to be going trough superconductive wire with no resistance, so the wire in submerged in liquid helium, liquid helium is always trying to turn to gas and boil off, the coldhead constantly re-condenses that helium as to preserve it in the magnet = the noise
Shame you can remember either of the actual effects...? just that, well, there was one effect, and, erm, another one... didn't you actually hear what the effect was exactly? just roughly? just to make it a slightly more believable read.... or perhaps just more entertaining than, I've heard of strange effect....and I've heard of other effects too....
?
Nothing actually reported in the whole time MRI has been used.... so, are you sure you're not telling Mr Porky Pies?
Since magnets attract ferromagnetic material, if you shot a FM bullet towards the magnet, the magnet might only accelerate the projectile towards the center (most powerful part) of the magnet. Are you asking would it prevent a bullet from leaving if you were already at the center and fired the gun pointing away?
Then, of course, there's the issue that most bullets aren't significantly composed of steel or other FM materials, and there's no attractive effect on lead.
I read that its inconclusive if MRI's contribute to tumour growth. There have been NO long term studies. As the MRI field is so much stronger than the entire planets, it makes me nervous to get one. I really don't wanna know what they might find anyways. Have already made appt & cancelled. Sometimes its better to not know.
They don't seem to contribute to tumor growth, otherwise we would have already seen more tumors in other areas of expertise like people who work at power plants, they face magnetic fields of up to 6 times as powerful as people who work with MRI's...
Huh? Now, if you bring too large of any ferromagnetic object (whether it's magnetized or not) too close to an MRI, it can trigger a quench because of the enormous physical forces exerted between the MRI and the ferromagnetic object. I don't know that anyone has ever quantified just how big, but there would be a number of variables involved.
dont you think they would have thought "oh, maybe we should put a magnetic material into your fillnings so the next time you go for an mri your face will be reduced to a piece of skin"
Dang, I had one of those today and I had to go pee during it so I was so happy when I saw the Doctor come in and say that I was done. I ran to the nearest bathroom after! I know they are sooooo loud!
Gauss and Tesla are measures of the same thing (think centimeters and kilometers). One gauss is 1 / 10,000th of a Tesla. So, translating what the speaker said, the Earth's magnetic field is approximately 5 gauss and the maximum magnetic field strength of the MRI is 15,000 gauss.
another reason why hospital grade metals are all non-magnetic, such as titanium, so that it doesn't pull your arm off if you have a metal plate in your arm
Why the hell have an 'Alan Wrench' in an MRI room? Hmm? It's a hospital, not a autobody shop! Do you have any other things to video, like how you may not have a brain in you head? Why not use the MRI machine to find that out!
hows about you try and use your brain a little better pal, ever heard of an engineer? maintenance man? you know the people who keeps everything working in the hospital???
them things aint nothin' to joke about you know, ive been caught in a situatuion where the fields werent turned off, a screw driver flew out of my pocket, thats how strong those fields are.

... A magnetic field cannot cause vibration or resonance, it can only force protons to line up in one of two configurations... This doesn't cause the release EMR... You need to actually input EMR at the right frequency, to make a proton flip states... Look up NMR, same principle.
Please KNOW what you're talking about before you post something.

that is true. to actually be able to manipulate the metal using magnetic force. the metal should have good magnetic properties and not a lot of metals have that, mostly its rare earth metals that have those properties and even then they are quite weak.

There's a neurovascular surgical tool that uses a pair of big electromagnets (on either side of your head) to help 'steer' a catheter through the blood vessels in your brain to deploy a stent or clip at the appropriate place.

I've heard of strang effects that people experiene when around such high magnetic fields. I've had an MRI, and din't notice much with it, but has anyone ever seen The Philadelphia Experiment? It was the moovie about time travel, and all of those generators were in use then. I've also heard of other effect that people have experienced in high voltage environments like this.

DO you know what the "pumping" noise in the background, when i had one in sunderland royal hospital's new scanner, i think it was 2 tesla, all i could hear was that when i was stepping into the machine!
yfrontluva 2 years ago
I don't know, but I heard a lot of clunking noise in mine in 1994! Not sure of what the strength of it was, at St. Johns Hospital in Detroit. I've heard people have noticed different effects when in an MRI that I've heard about over the years on Coast to Coast AM.

That is the Lquid Helium Cooling System
It cools the 1.5T Magent to almost -300 F or -400 C

Liquid helium recondensing, aka the coldhead, liquid helium is not actually being made colder, but when the helium tries to expand into gas the coldhead recondenses it into liquid so it does not boil off.
minusp 2 years ago
I fix MRI machines, the pumping noise is the coldhead of the magnet, basically the way that this magnet is a magnet, is by running current trough it, the current once in the magnet remains in there, in order for it not to dissipate it needs to be going trough superconductive wire with no resistance, so the wire in submerged in liquid helium, liquid helium is always trying to turn to gas and boil off, the coldhead constantly re-condenses that helium as to preserve it in the magnet = the noise

Shame you can remember either of the actual effects...? just that, well, there was one effect, and, erm, another one... didn't you actually hear what the effect was exactly? just roughly? just to make it a slightly more believable read.... or perhaps just more entertaining than, I've heard of strange effect....and I've heard of other effects too....
?
Nothing actually reported in the whole time MRI has been used.... so, are you sure you're not telling Mr Porky Pies?

I wonder if it would stop a bullet?
two4our5ive 2 years ago
Since magnets attract ferromagnetic material, if you shot a FM bullet towards the magnet, the magnet might only accelerate the projectile towards the center (most powerful part) of the magnet. Are you asking would it prevent a bullet from leaving if you were already at the center and fired the gun pointing away?
Then, of course, there's the issue that most bullets aren't significantly composed of steel or other FM materials, and there's no attractive effect on lead.

I read that its inconclusive if MRI's contribute to tumour growth. There have been NO long term studies. As the MRI field is so much stronger than the entire planets, it makes me nervous to get one. I really don't wanna know what they might find anyways. Have already made appt & cancelled. Sometimes its better to not know.
ophuichus2012 2 years ago
They don't seem to contribute to tumor growth, otherwise we would have already seen more tumors in other areas of expertise like people who work at power plants, they face magnetic fields of up to 6 times as powerful as people who work with MRI's...

If you had a plate in your dick, and it was made of anything magnetic, you'd get dismembered when they turned on the MRI.

Actually the scanner is always active, so it will dismember plate dick immediately.

How big of a magnet do you have to put in an MRI before it loses superconductivity and quenches?
raunchbear 3 years ago
Huh? Now, if you bring too large of any ferromagnetic object (whether it's magnetized or not) too close to an MRI, it can trigger a quench because of the enormous physical forces exerted between the MRI and the ferromagnetic object. I don't know that anyone has ever quantified just how big, but there would be a number of variables involved.

whats the gauss?
taliban0king 3 years ago
Gauss and Tesla are measures of the same thing (think centimeters and kilometers). One gauss is 1 / 10,000th of a Tesla. So, translating what the speaker said, the Earth's magnetic field is approximately 5 gauss and the maximum magnetic field strength of the MRI is 15,000 gauss.

another reason why hospital grade metals are all non-magnetic, such as titanium, so that it doesn't pull your arm off if you have a metal plate in your arm
