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?
hes going to have neck problems if he had lived, 20lbs on the neck will cause spinal deformities, and disc disease.
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
- 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.
They have extensive screening and education and safeguard procedures, for the patients. I’m guessing hubby skipped (probably wasn’t even offered) all those and just dashed in the door when called. Tech still should have put hubby through “the talk” if he was anywhere close to the door to the room.
MRI is one of the most sci-fi come to life technologies most people are likely to encounter in their lives. Superconducting magnets are about as non-intuitive as it gets, once they get you past the point of your ability to resist the force, there’s no recovery - you’re going faster and faster until the metal hits the housing. There have been multiple accidents with steel oxygen cylinders - for the obvious reason: they’re so common in the environment where MRIs are used, and it’s no small feat to get the cylinder removed.
Uhm, article I read said it was a training accessory and the wife had fallen on the floor and needed help.
But the husband was called to get her off the table? And she did help in trying to get him unstuck? How are there so many important details to this?
That’s it, as fun as it is to speculate, I think I’ll reserve my judgement until after this has gone to court.
The major failure in this case was lack of education / restraint of the husband. Before he got within 25 feet of the MRI room door, he should have had “the talk” about metal objects and MRIs not mixing, deadly consequences, etc. Other things could have helped, but I suspect the local safety procedures are patient focused and hubby didn’t get properly educated before entering the danger zone.
A 6 pound necklace…
1kg =2.2 pounds. more like a 20 pound necklace.
He didn’t see new Final Destination movie.
9 kilograms Necklace?! What kind of necklace is that?
A chain with a 9kg bell weight.
This was not Mr. T.
This was Mr. D Capitated.
Ooh mind you don’t cut yourself on all that edge!
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.the high powered magnet is always on. it’s never safe to put metal near and MRI.
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.
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.
Not to mention it’s not renewable. Once it his the upper atmosphere, you can’t get it back.
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
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.
Dont they loose the access to the machine anyway for few day? Im under impression metal slamming to the machine usually breaks it pretty good.
Well, the thing is, to kill the magnetic field within a few seconds would break the machine, so they don’t do that because it would up the cost of a shutdown from tens of thousands of dollars to several hundreds of thousands of dollars, and the downtime would go from several days to potentially several months.
As it is they “quench” the superconducting electromagnet, which then requires a large amount of LH2 and electricity to get going again. I have heard numbers like $30,000 to get the magnet running again, not counting lost revenue during the many days it takes to get going.
Well the thing is still that the weighted necklace pulled by 1.5 to 3 tesla towards the machine will also put it the machine out if comission from several days to several months.
Also the down time of the machine depend from so many things like availbility of components, logistics and the actual damage happened, that even the most pragmatic operator could never calculate the price of the repair versus the value of the possibility of saving human life.
FFS the saved 30k only buys pretty decent slightly used car. Its sick to even start to weight that kind of money to human life.
And in fact, doesn’t the US have most of the world’s supply of helium?
Its a superconducting magnet that cannot be instantly shut off. I am sorry that the physics of this makes you so angry.
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.
TIL, thanks
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…
Hospitals aren’t jails or high security government facilities. I could walk around a hospital right now and walk into an MRI room and nobody would physically stop me. I used to work in a hospital and we had a long meeting about signs, because a cleaner didn’t look at the door sign and walked into an MRI room with a metal floor buffer.
So glad to find that Lemmy is even less empathetic than reddit was. Real faith in humanity killer. Shocking how many people decided to comment without touching the article, really proud to be here…
Welcome to the freely accessible internet. I’m sure there are “private message boards” with much more rigorous vetting of their participants, if that’s what you need.
This is why our education system is under funded.
As if my claustrophobia wasn’t enough reason to irrationally strongly dislike the idea of needing to get an MRI again…
Who cares about a moron who needs a 9kg necklace, how’s the MRI machine?
It was for weight training
Yes, I remember the part in Pumping Iron, starring Arnold Schwarzenegger, where he was using a 9kg necklace in preparation for his role in The Terminator.
This is stupid. He knew his wife was getting an MRI. He was an irresponsible ass and ignoramus. What was more important? His wife’s MRI or his precious necklace weight training, at 61 no less?
And he had multiple heart attacks? The picture of health.
And now a MRI machine is out of order, how many people’s tests have to be rescheduled for one 61 year old’s fantasies of being a weight training badass? Your wife needed an MRI, put the high school jock nonsense aside for an hour or two.
“It was for weight training”. Fuck me.
Why are you being this way
Cube: MRI
Dude didn’t watch Final Destination Bloodlines 💀
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.
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.
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
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.
The dectector and the variable field (that induces the localized measurable changes) stop between scans, but the static magnetic field is kept up.
As long as you keep up the superconductitvity there is basically no electrical loss in the coils. Dialing the magnetic field down would require pulling out the energy, and reinjecting new energy to get the field back up. That’s the slow part, because injecting current quickly would heat the coil above superconductivity, leading to a quench.
I’m not sure how energy is withdrawn in the ordinary shutdown procedure, but I expect it is exchanged into heat and vented to the outside air in some way, rather than reinjected into the grid in a usable form. (The latter would require an inverter to turn the DC back into AC synchronized to the grid, probably would increase complexity by too much). So I suspect it would be wasteful too.
Maybe lockable doors
Idk bc some of the articles seem to be contradicting but apparently the door had a lock and the deck opened it
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. :/
the technician who made an honest but very serious mistake.
You mean letting someone in while the machine was in operation?
So many dumb ways to die…
Another Darwin award.
Only if he didn’t have kids.
Yah the guy was 61 so it’s unlikely that Darwin would figure into the consequences.
People misuse the term “Darwin Award” a lot. It doesn’t just mean someone died in a dumb way, it means they died in a dumb way before passing on their genes.
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.
