9 kilograms Necklace?! What kind of necklace is that?
This was not Mr. T.
This was Mr. D Capitated.
Ooh mind you don’t cut yourself on all that edge!
A chain with a 9kg bell weight.
The man, 61, had entered the MRI room while a scan was underway
How was that allowed?
he asked the technician to get her husband to help her get off the table.
…while the machine was still working? And isn’t that the job of the technician anyway?
the technician helped her try to pull her husband off the machine but it was impossible.
Those machines have a kill-switch for a reason.
I call this BS or a very incompetent technician.
Plus a Darwin award for the guy.Couple things:
The magnet is ALWAYS on.
The “kill switch” takes about five minutes to actually deactivate the magnet and it costs about thirty grand in helium every time you push it.
Isn’t it an electomagnet?
it costs about thirty grand in helium every time you push it.
Oh, right, i forgot human lives have a price in the US.
It’s a super conducting electromagnet, and if you quench it instantly pieces would be flying all over the room
Its a superconducting magnet that cannot be instantly shut off. I am sorry that the physics of this makes you so angry.
The US is an outlier in how it charges prices for healthcare services.
But every country in the world has prices charged for cold liquid helium. It’s very expensive to gather, process, store, and ship, regardless of what kind of health care economics apply in your country.
Not just the helium, there’s a considerable time spent “recharging” the magnet with electricity - many patients will lose access to MRI scan service during the multiple days it is down for recharge.
Depends on the machine type. Closed bore machines (the vast majority) use supercunducting electromagnets that are surrounded by liquid helium that creates a very strong magnetic field. To demagnetize them requires dumping the helium.
Some open bore machines use electromagnets, but they’re much less common and not as powerful.
So the helium itself becomes magnetized, is that it?
the helium is liquid, which it only is when it is very very cold.
The superconductor will keep it’s magnetic field forever, as long as it’s superconducting, and it will stay superconducting while it is very very cold.There is physically no way (as in, it is simply impossible, due to how our world works, not money, not people, not technology) to instantly “switch off” the magnet.
it needs to go above a certain temperature, to lose it’s superconducting nature, and it needs to do it at a pace that doesn’t dump a GINORMOUS amount of energy in this magnetic field instantly, because that would be even worse.
the fault here is in allowing anyone with any magnetic metal anywhere near an MRI. And whoever let that happen is going to have a very bad week.
No, the liquid helium cools the magnets to the point where they become superconductive. As to how that works exactly, I do not know. I don’t think I have the math for it.
I’m sure he was barely trained and had specific instructions to “never push that button!” When you whole life in the country is tied to your employment, it’s every moron for themselves.
It’s not an electromagnet, it’s a superconducting magnet. And turning it immediately off makes it melt.
It’s both! MRI magnets are electromagnets that are cooled down to 4 Kelvin using liquid helium. Once they reach those low temperatures, they become superconducting. This way, the magnet isn’t gobbling up tons of electricity to stay at the desired field strength. Instead, the liquid helium needs to be replenished occasionally to keep it at superconducting temperature. Source: I work with MRI scanners.
The kill switch is VERY expensive to press, many thousands of dollars, and even when it does an “instant” magnet quench, by the time you hear the screams it’s all over anyway, the metal has landed on the magnet. Quenching the magnet will make it let go, but it won’t unbreak the neck bones.
What kind of hospital let him get near the room with that kind of metal around his neck? I’ve had to be in several hospitals recently for different imaging issues and every time the MRI is a thing I have to remove everything metal to go past a certain door (escorting my daughter and son for medical reasons). I don’t know who let him anywhere near the room with something that large.
Edit for Clarity: I’ve had to be the one removing all metal even though I’m not the one being scanned. For me to progress beyond a certain part of the hospital toward the MRI I needed to get rid of everything. My children were being scanned, not me. So, I’m not sure what hospital system allowed this man with a 9kg chain get this far deep into the imaging area.
He wasn’t supposed to be in the room. There was a scan in progress when he entered.
Seems to me all they needed was a magnet of equal or greater strength placed opposite of, and perhaps a bit closer to the doorway, to pull intruders away from the MRI room.
His wife told News 12 Long Island in a recorded interview that she was undergoing an MRI on her knee when she asked the technician to get her husband to help her get off the table. She said she called out to him.
Whole thing is heart breaking all around. I feel for the technician who made an honest but very serious mistake. And I’m sure the wife will spend her days regretting asking for help. Just a fucking tragic situation. :/
all they needed was a magnet of equal or greater strength
MRI magnets are electromagnets that are supercooled with liquid helium and take hours to start or stop because of the electrical energy that has to be put in or taken out.
So just having a magnet of equal strengh for idiot defense would be a very significant waste of electricity and helium unfortunately
But it would be funny
take hours to start or stop
You mean they’re in constant operation the whole shift?
Surely dialed way down in between scans?No, the magnets are just as dangerous when scans aren’t happening. They are always on.
Surely 9kg necklace isn’t something you can just sneak around with, how was he allowed to get close enough to an MRI machine in the first place wearing it?
I would need an entourage of physiotherapists if I had the bling to roll with a 9kg necklace.
Imagine how dope my rhymes would be though. A man can dream…
So many dumb ways to die…
9 fucking kilograms!? For my fellow Americans, that’s almost 20 pounds!
I feel like someone should have noticed. I’m pretty sure I’ve never seen someone wearing a twenty pound necklace.
I always knew Roughneck McGee would meet a tragic end. Ironically he wasn’t even wearing his BIG necklace.
Can you convert that to tennis balls? I can’t do this math on my own
Somewhere between 150 and 160, depending on the tennis balls. Hope this helps

Edit: Additionally, that’s about 63½ European swallows, assuming an average weight of 5 ounces. Given that a European swallow must beat its wings 43 times per second to maintain airspeed velocity, it’d be a proper racket.
Tap for spoiler
Those numbers are from monty python and the holy grail and are very wrong. I am spreading misinformation online.
And if it’s an African swallow?
Not covered in the film and I refuse to get my information anywhere other than Monty Python. The mass of an african swallow is therefore unknowable.
It’s a fair cop
Dude didn’t watch Final Destination Bloodlines 💀
Carrying a 9kg necklace seems a bit silly. Though I suppose “for weight training” could just as well mean something medical, like needing to build up muscle mass after an operation.
What I need to know is: how is a man that was “not supposed to be in the room” specifically getting fetched by a technician to go into the room? I would have said “do not go past the antechamber” a dozen times on the way there. Did the wife calling out to him just turn off his brain, did the technician fail to inform him, or did they both not realise the metallic necklace was on him?
After reading another article: nope, necklace was just a huge locket on a chain. And the wife said “Keith, Keith, come help me up” which sound to me like:
- wife was making a big fuss for no good reason (might have had a reason according to a 3rd article)
- husband obeyed as any good husband would
- technician didn’t inform the husband that his wife would be carted out of the MRI room and failed to react fast enough
If I was married and a bit dumber, I could probably also be lured to my death with my name being called out twice in that fashion. Really depends how good the signage was and how well the husband was informed.
We need a /c/NotFinalDestination, this is literally one of the scenes in the last entry to the franchise.
He didn’t see the new Final Destination movie.
I… want to see that 9 kg necklace. I mean, sounds like it’s just a big-ass chain, but if so, how did it not throw up red flags all around letting this guy wear it around that machine.
9kg is around 20 pounds. what, did he have a kettlebell as a pendant?
the answers to all your questions lie in the article you didn’t read
The article doesn’t really answer much about the necklace though. I want to see a picture of it and understand why the fuck someone would wear it. Like “for weigh training” but what the fuck is he exercising on a random day in the hospital.
Okay 3 things.
-
9 kg is 2.2 lb, which is ridiculous, and can’t be good on your neck. The article says 20 lb, so one of those is wrong. I’m gonna guess the metric one is writing since in America we measure everything in Freedom Units™
-
Did the “no metal” warning sign go missing or was he just illiterate?
-
That must have been a horrible mess to have to clean up.
Dude, 1 kg = 2.2. Multiply that by nine and you get 19.8 lbs.
9kg is almost 20lbs, which is even more ridiculous
-
Was the necklace even related to the death? It says he had a “series of heart attacks” which doesn’t sound like something caused by being pulled toward the machine.
If the necklace impeded blood flow or even put a lot of strain on his circulatory system then it could have caused his heart attacks.
Sounds like it wasn’t him being pulled towards the machine that killed him, it was being pinned against the machine for a prolonged period of time.
yeah what annoyed me was the Lady asking to just turn it off like you can just turn it off. i know she is desperate to undo her and her husband’s stupidity but the article framing those quotes like the tech was incompetent is bad journalism.
You absolutely can turn it off - it’s called quenching the magnet, and the tech absolutely should have been trained to do that in an emergency. There was no way in hell they were physically pulling him off. It’s obviously that they did eventually, but the article doesn’t say how long it took 🤷♂️ to be fair, I’d bet that basically all of the damage was done up-front, regardless - MRI magnets are so much stronger than most people realize.
Easy solution : have a pure gold necklace, since gold isn’t magnetic
18kt gold is an alloy with 75% gold and other metals that may be magnetic. I wouldn’t trust a gold chain around my neck with an MRI.
So, if the MRI spins at 12 RPM, does the dude also spin at 12 RPM?
Asking for a friend.
The detector spins around the patient, but does the magnetic field spin too? I though not, but I’m not that certain.
Nope, the detector is separate from the magnet - the magnet encircles the patient completely, and doesn’t move. I’m sure the magnetic field is affected slightly by the rotating machinery, but that should be consistent and predictable, and would be accounted for in the imaging algorithms.
Yeah I considered the supercooled electromagnert couldn’t possibly rotate, but I wasn’t sure if it could be modulated to change field directions or something. Didn’t seem very likely. Thanks for the confirmation.
Did no one else read the story? I read it and it sounds moreso the clinic’s fault
The necklace he was wearing was a steel weighted exercise band, not a normal necklace. He’s not flexing his wealth or anything
His wife told News 12 Long Island in a recorded interview that she was undergoing an MRI on her knee when she asked the technician to get her husband to help her get off the table. She said she called out to him.
Seems like the technician was told by the wife to bring her husband in to help her up. The technician/clinic made a mistake by letting in the husband, who didn’t seem properly warned about MRIs no metal policy. The technician also somehow didn’t catch the giant “necklace” he’d be wearing.
The “he wasn’t supposed to be there” seems like a coverup for their mistake, since how else would he have known to go in? Someone must’ve told him to walk into the room, it’s not like he could hear through the door.
I’m not saying it’s the husband’s fault, but I don’t think it’s 100% on the technician either.
I read it more like she asked the technician to get her husband and called out to her husband who presumably just walked in.
Also, “they discussed the chain on a previous visit” doesn’t really change anything. Depending on how many people that technician sees and when that last visit was, they might’ve just forgotten.
