Original: Why You Never Take Metal in MRI Scan Rooms - Metal vs MRI Safety Demonstration
Vložit
- čas přidán 22. 07. 2018
- It's MRI vs metal in this video showing why bringing metal in MRI rooms is never allowed. This test was performed in a 1.5T mobile MRI with a lanyard and paperclip. Loose metal in the MRI scan room is a safety hazard and should be removed from the room immediately. MRI scan safety standards should always be adhered to. Please do no attempt to recreate. It was pretty difficult trying to keep the camera focused, in-frame, and narrate at the same time, thank you for bearing with me.

As long as its not made of something magnetic, mainly steel, the MRI is safe...
@@Dodo-ze5ep crazy that I’m seeing your 3 hour old reply on a year old comment just now. But, you’re wrong. No camera is made without magnetic material
@@cade8986 Yes of course theres always something magnetic in virtually all electronics, but theyre very small and dont get effected by a magnetic pull very hard. And I didn't even say that a camera isn't magnetic, when you read closely...
@@Dodo-ze5ep it has platings and components that are incredibly magnetic, that are so sensitive even the tiniest pull can cause catastrophic damage to them
@@bingus6542 Not realy, the sensor and its electronics are all solid state components that contain next to no iron, they don't realy get affected.
The shutters wich ofte are made from non-magnetic titanium and the mirror don't move at all when shooting videos.
The body is usualy not made from steel/iron either, it's either plastic, aluminium or magnesium.
The lens mount might be made from steel, but it's a pretty tough part.
The lens itself may have some structural parts made from steel and the magnetic field might upset eventual image stabilisers, but not cause fatal damage.
A camera should be able to handle exposure to magnetic fields.
Because of the metal fillings of the cavities in my teeth, the MRI machine reversed the polarity in me. Now I walk upside down.

lmao true
The janitorial staff at one of my MRI sites decided it was a good idea to bring a floor buffer into the magnet room. Yes, the magnet liked the floor buffer. No, it wouldn't give the floor buffer back until we ramped down the magnet. Some damage did occur to the covers on the magnet but fortunately, the magnet itself wasn't damaged.
I heard of a similar incident in the U.K. - by intentional design no socket outlets are installed in an MR room so there is nowhere to plug in cleaning equipment but one cleaner showed some initiative and used an extension lead...🤪
New generations of MRI machines are cooled with helium. A full restart requires helium recharge which could cost $50,000.
@@xinfuxia3809 MRI scanners have been cooled with helium for years so not a new thing. Releasing a cleaning machine (provided it wasn't pinning anybody to the magnet) wouldn't be classed as an emergency so there would be no need to quench, the magnet would be ramped down by a service tech., the cleaning machine recovered and the magnet brought back up.
@@xinfuxia3809 All of MRI machines use liquid helium. We maaaaybe are going to get the first small-scale units for head MRIs cooled by liquid nitrogen some time next year.
I imagine they make the housing for the magnets extremely strong. A helium leak would potentially be fatal, displacing oxygen from the air. Not to mention the risk of having who knows how much cryogenic liquid spill on a patient.
In cases where failire woild be fatal or catastrophic, things are usually engineers to withstand more abuse than they could realistocally be expected to experience during its life.
Since we're talking coils, just a pad-mounted transformer, or of those green electrical boxes, is built strong enough to be hit by a truck. And those are just full of mineral oil. Not liquid helium at less than 4 kelvin.

My goofy butt would totally do this!
I remember last year I was having one done. Like an idiot, I wore steel-toes to the appointment. The nurse had me positioned in. As she was starting it up ,she realized I had the boots on. She told me if had I continued it would’ve broken both my legs. It’s a scary afterthought.

Crazy because I had one last week and they left my belt buckle on. Ruined my bank card but other than that, no issues.
@@Boethius411 Probably a non-ferrous belt buckle then I guess?
@@noxious89123 nope. The scan was just of my head. I could feel it pulling
They shows have never let you into that room with those boots. Most scanner rooms should have a metal detector to prevent any mishaps
No metal, or phones, watches or even credit cards should go anywhere near an mri. It destroys it for good
I respected this and took off everything….
That’s not entirely true, as you see in this video. (And if you’re about to get a brain MRI and is having trouble getting your ring of, it’s ok to leave it on as long as it’s not getting warm.)

I do and my dr almost had me get an mri instead of ct. I have titanium for my orbital floor and eye socket. I am so scared to ever get in. Car accident now.
@@shannongrose9016 titanium isnt magnetic. Thats why they use it for implants. Ive got 6 titanium screws in my spine and ive been through plenty MRIs without getting them ripped oit
Dennicam24 yeah I’m gonna stay clear as instructed by my surgeons....
@@dennicam2428 It's more complicated than that. While non-ferrous metals won't get pulled through, they can still rapidly heat up. They'll also cause massive artefacting on the scan.
@@lost4468yt Well yeah, ive noticed slight discomfort whilst in an mri. The Pictures are pretty clear tho, and the doctors even told me themselves that theres No risk in going in there
Ah so cute! Going for a walk with his Office Assistant. What`s his name, Clippy?
Exactly what I was thinking!!
It looks like you're getting an MRI! Would you like me to do the questionaire with you, to make sure you're not wearing anything that might be dangerous in the MRI room?
Depending on the Pt. an X-ray of the eyes are done to demonstrate that there is no metal fragments present. Otherwise there could be an ocular injury.
I had to go in to get an MRI a couple years ago and had a panic attack that the rod and screws that are in my leg was going to blast out and obliterate my leg! They had to give me some good anxiety meds and finally got it done, I still have my leg 😂
The only thing i remember is I did feel like that leg got very warm
You can happily enter any MRI room with metal. Just make sure it's non-magnetic.
@@jdeep7
gold is non magnetic metal.
@@noorazmi2329 Just not enter with something made of iron, nickel or cobalt.
@Joakim Matthew N. Castillo steel is magnetic lol
@Joakim Matthew N. Castillo SHUT UÜ
I've got a metal retainer in my lower jaw. Whatever metal it is, it is MRI safe. Tested several times for you. If a patient has any metal on / in his body normally a certification is required that it's MRI safe. Otherwise it's dangerous for the patient and very expensive for the hospital to damage their million dollar device. If uncertain, no MRI.
There is a superconductor providing this magnetism and it does not use site power.
What is running is the coolant pump keeping the superconductor at the needed temperature.
I was getting an MRI done and the tech told me that.
I had one on my right foot in 2012. The hospital facility had a separate three phase sub simply to supply the current for the superconducting magnet and the associated cooling equipment.
@@paulanderson7796 you are both correct. MRI is ramped up using a high amperage power supply and energy is stored within the superconducting coils of the magnet. 480v 3phase supply is used to power the PDU assembly, gradients, operator console, systems cabinets, and the coolant pump that you can hear running in the background. Smaller components typically use 110-240v stepped down from the 480v.
I hurt my back several years ago and my doctor offered to do an MRI. I told him I didn’t think that was a good idea because when I was born, the duct or valve, or whatever it is, that pumps blood to the fetus’s lungs did not close. I was implanted with a clamp of some unknown material to close it. This was in 1981 so I’m not sure if it is metal or plastic or what. I just did not want to take that chance and turn the MRI machine into a raw meat factory. Actually, I’m curious to know what would’ve happened if anything?
If it was a non-ferrous metal implant like titanium it would have done nothing. If it was a ferrous metal implant, your implant would have ripped itself out.
If it was magnetic, the mri would pull it and rip the part of the heart ripped apart. It probably isn't though
It’s very unlikely metallic. You’d be setting off all sorts of alarms in airports and stuff if it was. Would also show up easy on an X-ray.
Better safe than sorry though! If you are at all unsure go back to your doctor and ask for an X-ray or CT.
@@asdfssdfghgdfy5940Stents are often made of metal.
@@asdfssdfghgdfy5940i got metal plates and screws in both legs and it never set off a metal detector it's disappointing actually
Don’t be shy. Let it go
I know right, when I was in the Hospital, I asked what happens to the MRI if metal is near, they said that it can break and it's very expensive to repair or replacing

Ergh I had a nightmare about one of these. I dreamt that some idiot had left a ring pull (from a can of coke or something) on the bed. When I lay on it and it came on it slice through my body like a scalpel through butter. It wasn't real but I woke up with a headache lol
Jesus...
Well thankfully aluminum is not magnetic so you don't need to worry about that happening anytime soon haha
An example of Final Destination movie scene
Good it was a dream
The PCB inside the phone has a lot of twists and turns that can act as a crude transformer and generate electricity provided that the cell phone moves enough to generate an alternating magnetic field. There's probably a way to fry the cell phone next to an MRI if you spin it or rotate it at just the right speed to generate sufficient energy to fry a chip or put electricity where is shouldn't be or at a level is shouldn't be at.
He's not really moving the camera around that much so any internal electricity is probably at a minimum but it could still be enough to crash software running internally if a 0 becomes a 1 or vice-versa.
Really fascinating stuff! MRI machines provide you with 5-10 tesla of magnetic strength that is an order of magnitude greater than the strongest permanent magnets. Probably a lot of fun science experiments you could do with an MRI machine.
I'd really love to see how far away a compass would deflect from an MRI machine.
all phones have shielding over sensitive parts so most of that argument is irrelevant, also fixed magnetic fields won't do much, the fun stuff happens when you have switches fields like found in a ZVS driver often used in induction heaters

You call it the magnet.
I call it The Force.
I had open heart surgery in 2013 and the sternum is closed back in place then fixed with sternum wires, which I believe are nickel. Nickel, however, is attracted by magnets, so it probably wouldn't be a good idea for me to undergo an MRI scan.
I appreciate this information, thank you. But I’m wondering why the machine makes so much noise. It’s kind of scary when you’re inside of one of those things. Also, why can’t you go in feet first, to offset the chance of claustrophobia ? My granddaughter had to have an MRI after an accident several years ago. She is claustrophobic and had to be sedated before she could have the procedure.
Love that he shows the rock horns hand sign \m/
they figured out "magnet shielding". closed coil of the superconductor has reverse turns at the end faces. that is good - the magnet weakly attracts (almost doesn't attract) further than four feet. and that is danger - magnet abruptly suddenly powerfully attracts if your iron thing closer than two feet.
and the "slurping" is a "cold head" sound, it liquefies the helium gas back into the cryostat w/superconductor coil. this is a complete recuperation of helium without loss. helium is very expensive.
I wonder (not that I recommend doing this) if you threw a cloud of iron fillings would you see the field lines for a split second before they hit the MRI machine.
Thanks for this video..! :D

That was a mobile MRI, according to the description. Very interesting definition of "mobile" lol.

Another reason I choose to wear either surgical steel or titainium earrings & septum jewellery, one less thing to think about (and I don’t have to take them out and risk the piercings closing). Like with metal detecters in airports etc, my piercings dont set them off. Plus I dont want my head to go flying into one of those beasts 😂 I rarely have x-rays or MRIs etc but still.
My sister had back surgery when she was 8 yrs old, it was a new technique back then, they never told my mom nor syster that they had inserted a metal rod in her spine on top of fusing all her spine together. 1 day a doctor sent her for an MRI and she then developed more pain in her neck, the doctor was shocked to find the rod was in there, so doctor 2 yrs later told my sister she needed another MRI, like I stated to my sister "but did she not tell you that you have a metal rod in your back", my sister then stated your right, she called her doctor and the MRI was canceled. I have a clip inside of me from gallblader surgery, so each time I have an KRI done, they put my back to the machine and test if the clip moves or hurts me, it appears my clip is not a metal which is affected by MRI as I have had 3 MRI so far.This is why I did not understand the bombing of a hospital, which stated they had hidden weapons behind an MRI machine, there is no way this could have been done safely, if it pulled a paper clip, imagine a machine gun and the bullets and whatever else those were in ?
She developed neck pain after the MRI?
@@IosifStalinsendsyoutoGulag After the MRI the neck and shoulder pain increased even more, on Xray post MRI they saw the rod had dislodged a bit. She was fused from C3 down the whole of her spine at 8 yrs old, because of severe scoliosis (more then 90 degrees deviation in her spine), so even if the rod dislodged a bit, she was still fused, they did the MRI to see if they would have to fuse the C1 and C2, as one of her clavicules is completely loose as the cartilage no longer exist to hold it in place, so that arm does not work well anymore (yet she still works full time job standing up as a cashier in a pharmacy). Back then her spine surgery was new, so new they flew in Shrinners doctors from Mexico to teahc the technique to doctors here, so my sister was a guinea pig of sorts I guess as she was the first one having that procedure done back then. Also back then there was no MRI machines hence why her rod may be from a different material which is used in this day and age. I myself have metal clips when they removed my gallbladder but I have had 3 MRI's myself and nothing ever happened so it is made from a compatible material with the MRI.
Why do MRI Rooms, (In NHS Hospitals, Childrens department, idk if adults dept have an anaesthetic room too) have an anaesthetic room next to them, & a big thick metal door?
Can this machine pull a metal tooth with the speed of a bullet from the mouth ? Please i am curious reply
I have a septum peircing and I don't know how to take it out and now I'm kinda scared, do u think it will affect the machine if I'm getting an mri on my foot?
It is hard to say without all the details but I would assume the tech would not let you enter the exam room with piercings on. Is the piercing made of ferrous material? You can try taking a small magnet to the piercing and see if it has an effect. Is your septum sensitive if there is any movement in the piercing? There is a chance it could be made with nonferrous metal so all good questions to answer before exam. If you are scanning your ankle you will be entering magnet feet first so it will not affect image quality but I’m a little concerned about the safety aspect and would err on the side of caution before proceeding. Imaging centers will normally run a metal detector during the prescreening process and they will provide a definitive answer. Good luck with your exam. I hope this helps :)
Another question : this equipments are high tech, I wonder :doesn't them have some kind of detecting phase before going full power, to detect metal parts on the body?
No
The magnet is always on so there is no way to turn it off even if there was a detecting phase before going full power: It's always at full power 24/7.

You can take metal into an MRI, just not ferrous metals. I got to keep my ring on when I got one because it's titanium, just felt a faint vibration of it while the machine was running, but no strong PULL
I have a question: I had a heart surgery, open chest type, they had to tie my ribs back together with a metal wire. But I have been to this machines and nothing happened, how is that soo?
The metal they used was medical grade and not magnetic
I had molybdenum screws implanted in shoulder surgery. Need an MRI now and the tech said screws are not magnetic, but I think the screws are basically steel with molybdenum as an additive so they would be magnetic. I told the tech. that I had the moly. screws and she said, "what is molybdenum". So if she doesn't know what it is, how can she know if they are magnetic? Don't know what to do - right now have postponed MRI.
I researched this quite extensively but unfortunately have no prior experience with molybdenum alloys used in implants. I would love to know what you find out and if there are any imaging limitations. Thank you for sharing. Good luck!
@@MRIPETCTSupportEngineer thank you for your research and your response. Unfortunately, I used to work as an entry level employee at a ship water pump manufacturing company in Oregon. I had to grind out the interior of the pump castings to ensure they were perfectly smooth, and once I got s shard of metal in my eye while showering after work. It was washed out and checked with a special light to be sure all metal was removed, but the MRI prep person said that since I had that experience I would have to come back at another time to have my eye imaged with a different system to ensure no metal was still in my eye. She had no idea what molybdenum was, and that did nothing to reassure me. Between the Molybdenum Steel in my shoulder and the new issue with my eye, I have decided not to go forward with the MRI.

I saw on the nightly news that in Gaza, rifles and steel ammunition magazines were store behind an MRI machine. What would happen to them if the machine was activated?
That’s a great question! I have been getting similar comments on the channel and I have been reluctant to comment because the issue has been so politicized but I can provide some clarification. If the MRI was activated, I would expect those items to be stuck to the side or front of the magnet. One of those big items would be almost unmanageable by a person inside the powerful magnetic field, let alone a big duffel bag. Also, firearms are known to/have a high likelihood of “spontaneous” discharge when exposed to powerful magnetic fields. However, I don’t believe the magnet was activated at the time the video was filmed. I hope this provides some clarification on the issue. Thank you for the comment!
YW. Thanks for responding to my question! Of all the places in a hospital to stash something like that, I have to believe that location was far from the best. Maybe a janitors closet or somewhere in the kitchen or almost anywhere else might have been far better. LOL!!@@MRIPETCTSupportEngineer

I would recommend to ask your imaging center but can offer some insight. Generally the biggest safety concern is with loose metal that can either be pulled in towards the magnet or cause RF burns on the skin, or in this case the inside of your mouth. With some special precautions, I'm sure everything will be okay but you definitely want to let the imaging center know during the patient screening process. Good luck with your MRI scan!

@@Myopicvisions wow after 8 months someone finaly replies! Thanks XD
@@ALMarkAZ1990 sorry, I just saw the video yesterday.
what about people with metal arms or legs?`?
Can it be turned off, or it`s a permanent magnet?
Well, it's a long scientific process to energize it because it must be cooled to super conducting temperatures, and then the current through the main coil slowly ramped up with a special power supply made just for this purpose. Liquid helium is a common coolant for this. As the current circulates through the main coil, it becomes a super magnet. Now, power is needed to keep things that cool, but a loss of power won't instantly kill the field. However if it was off for long enough, it would heat up too much to still be a super conductor. Then the coil would rapidly heat up to the point that the liquid helium would boil off and break the pressure relief valve, and it would escape through a roof vent. This is potentially damaging to the MRI if this happens, therefore it's something that a hospital or lab would want to avoid if at all possible. They can trigger it intentionally to save a person's life, however, if they are pinned to the magnet by a metal object.
Thank you! That was a great explanation of the process.
IF you can't bring metal into the scanning room why have they put metal coat hooks on the wall???
“And looks like cell phones are pretty safe” lol yeah you’re lucky there’s no large amounts of magnetic material in phones.
But what do you do if you get a pasient with battle damage, like shrapnel damages?? only x-ray??
Ultrasound, palpation, or exploratory surgery.
But iron in blood is ok.
Would that explain the weird patterns I saw with my eyes shut?
Nah that's just you being dehydrated
I am confused with metalic objects. First, a badge containing metal at the tip. Second, a jacket with metalic zipper. My MRI technician swings his badge, containing a metal at the tip, as exactly as shown in this video almost 1 minute before my procedure. In addition to that, the technician has a jacket with a metalic Zipper. Is that a safe procedure?
Some metallic objects are strongly magnetic, called ferromagnetic, such as things made from iron, cobalt, or nickel, among others. Some metallic objects are not ferromagnetic, such as titanium, aluminum, or copper, among others. While these other metals won't be attracted to the strong MRI magnet (which is always on at all times btw, whether or not a scan is happening), during a scan some metals can potentially heat up and cause burns, so that's why even non-ferromagnetic metals are a possible concern for the patient but not necessarily staff.
Our staff, same as the patients, isn't allowed to wear anything with metal. No zippers etc on hospital uniform. The nurse going inside with patients for sedation for several hours even only wears sports bras on that occasion to avoid problems.

@@iremaslan3607 It would be difficult to assess without more information, but I can give you some insight. it is typically not recommended for any metal to enter the MRI room but there are many factors. Is it made of ferrous metal? Is it fixed in place? Is the imaging center already aware of the piercing? The main safety concerns would be the magnet pulling the piercing off, RF burns due to metal vibrating and image artifact caused by resonant noise created by reflecting RF. If you can remove it for about 30 minutes, I would try to take it out but the best option is to call your imaging center and let them know. It’s something they deal with in a regular basis and they will be able to provide you with the best answer.
@@MRIPETCTSupportEngineer Thanks for be interested.i talked to the hospital.It is very difficult to talk to hospitals where I live.They said there would be no problem.my head is out of the machine because the problem is in my waist.sorry for my bad english :/ Thank you for your interest and concern.
@@iremaslan3607 Great to hear! Good luck on your upcoming MRI scan!
That magnetic field is so powerful It can pull a wrench through a wooden door, two, if one of them is open.
This is the reason why im scared of mri's
