Geez, imagine how much it would cost to repair.
This is in the US, so about as much as the exam itself.
It really sucks, but of course it was an idiot from Nassau county 🙄
For anyone who might not know the area, Nassau County is the place that gave us George Santos. It is burgundy-red, only bested in racism by Suffolk county. The police departments are notoriously racist and will pull you over and interrogate you just for driving a beater. This was one of Trump’s favorite police departments during his first term, he infamously told them to bash people’s heads against their cop cars when arresting them.
Sadly there are many very left leaning people trapped on Long Island, unable to leave because LI is an employment wasteland. It’s not cheap to live on LI either.
Anyways, an idiot from Nassau won’t be missed.
Do not forget it was LI was basically kkk hq for a while.
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.
9kg is almost 20lbs, which is even more ridiculous
Dude, 1 kg = 2.2. Multiply that by nine and you get 19.8 lbs.

We need a /c/NotFinalDestination, this is literally one of the scenes in the last entry to the franchise.
Came to say the same. Probably not the first but definitely the first I can remember a headline about.
In the case of FD, a different part gets injured in that scene.
9kg-metal necklace
Did he drag his knuckles?
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, an all aluminum chain then?
Easier solution: take off your damned metal necklace.
Moving fields, eddy currents still apply.
Copper isn’t magnetic either https://www.youtube.com/watch?v=Yu1uRvErM80
Well, TIL. There goes my hopes of showing up to the MRI room with a giant gold necklace
Ehh, if you’re gonna go, it’ll at least be memorable :) I suspect we’ll both pass without even a lemmy shitpost.
9kg of gold is worth close to $1mill. Mr T is baller enough to do that
The best part about Mr. T’s gold necklaces is that he got the idea from working a bouncer. The man became a literal living mannequin, holding onto people’s gold chains like some kind of ass-kicking coat check.
it mustve been ferrous material, because gold isnt super magnetic. like steel or iron.
Apparently the chains started when he was a bouncer. Sometimes people would lose them, while getting kicked out. He would wear them, so that had to come and ask him politely for them. His collection built when they were either too scared, or too egotistical to ask for them back.
That’s the story he told the news in the 80s after he was famous…
If you don’t think Mr T was playing Debo, I don’t know what to tell you.
IIRC Mr T stopped wearing his gold chains because he came to feel that they were tone deaf.

This is why our education system is under funded.
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
Why wasn’t the door to the room locked while the machine was running?

How else is he supposed to get the premonitions?
while the machine was running?
In an MRI, the magnet is always on, even when the machine isn’t running. You can’t ever go near it with metal on.
the magnet is always on,
I keep seeing that in the comments but isn’t it actually an electromagnet?
Don’t those need electricity to operate?I get it takes time to wind it up, been inside a few myself, but surely there’s a kill switch?
Its an electromagnet that they have cooled down to 4 Kelvin with liquid helium. They take time to ‘wind up’ aka ‘ramping up to the desired/max field strength capable of the magnet’. They do this slowly because the magnet itself can crack if done too quickly, and many components are still affected by the strong magnetic field due to Lorentz forces. Also many components may be classified as ‘non-magnetic’ but still have some small amount of magnetism and can move when subjected to the extremely high magnetic fields. So, if the magnet is ‘quenched’ (all the helium shot out through a tube in the roof) then that process occurs in reverse, VERY quickly, potentially destroying many things. So its not like ‘cutting the power’ because the power is stored around the magnet itself by supercooled components creating a superconducting situation. Nonetheless, in case of harm coming to a person, techs should absolutely hit the quench switch. Not sure what happened to allow this guy in that room though
It would probably be quicker for you to look it up yourself because the answer is complicated to explain. But it’s an electromagnet made from superconducting materials, and that is why it seems to violate your common sense.
Tldr for safety
To actually answer your question instead of piling on, it’s a hospital, not a prison. In case of emergencies, the door absolutely cannot ever be potentially locked, even while the machine is on.
With how easily something can go wrong in an MRI, they need quick access without the addition of special keya/badges to get inside or relying on people inside to hit some lock release.
In cases like this it makes perfect sense to have a lock because an idiot was outside and ignored all the warnings. A lock would have prevented everything that followed him entering.
Buuuuuuut unfortunately we can’t cater the entire world to the biggest idiots, if only for the safety of the less idiotic who might have a heart attack in the MRI and need to be quickly pulled out, or a piece of metal that snuck into their food and is now ripping out their insides.
In most situations where an emergency happens inside, quick reactions save lives, and locks slow reactions down to the slowest mechanism, which might be “I don’t have the right RFID badge, go find another person who has one or the guy inside dies”
A 6 pound necklace…
1kg =2.2 pounds. more like a 20 pound necklace.
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.
So, if the MRI spins at 12 RPM, does the dude also spin at 12 RPM?
Asking for a friend.
I imagine his head was plucked like a ripe tomato in the garden.
I doubt it, obviously depending on the applied force.
Skin is rather tough to rip with a blunt tool so yeah, maybe the head was disconnected from the spine immediately, making him look like a giraffe spinning at 12 RPM round and round.
Just going through comments spreading MRI information (source: I work with MRI scanners). Nothing is spinning inside the MRI machine. CT scanners have an internal spinning component, but MRIs do not.
Thank you, I actually did not know that. While we are at it: what is causing the sounds? And how often do those machines have to be calibrated, as I believe the RF receivers (?) have to be super sensitive and accurate.
The sound is caused by ‘gradient coils’ that are being switched on and off at kHz frequency, which is in the audible range for humans. The sound is caused by those coils vibrating due to the interaction of the magnetic field with the electric current in the coils: they’re non magnetic but they still feel the ‘Lorentz force’. As far as calibration, there is a pre-scan step (which is one reason why MRIs can take awhile) used to optimize the RF settings to each patient. Patients come in many shapes and sizes so the settings have to be tuned to get a good image every time. I’m actually not sure of how often they need to be serviced, but it seems like the manufacturers are here checking on the machines pretty often!
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 would be accounted for in the imaging algorithms.
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.
