Um, ok.
Turns out, it's pretty relevant to the situation - especially how the unauthorized access was possible.
This wasn't your typical hospital MRI. This is basically your local tanning salon that somehow acquired an MRI machine.
I don't understand how such a dangerous machine can end up in a place that looks like that.
The superconducting magnet in an MRI scanner is always on even when not performing a scan.
This was pure and simple negligence by the MRI operators. Access control is the most basic part of MRI safety!
Even if he was not wearing this “chain”, he never should have been allowed to enter the room. He could’ve been wearing a steel wristwatch, had a keyring in his pocket, etc.

According to the above post, it's a venting of the liquid helium, which requires ~$25,000 to replace).
I’m not sure what kind of emergency would warrant allowing metal to pass through when metal is detected, if there is a risk of death for using it.
The risk would be in the false positive during an emergency situation.
The journalist missed a golden opportunity for education here: most MRI scanner magnets cannot be turned off like that. For the few that can, it's going to cost >$50,000 just to refill the liquid helium, not to mention the real and opportunity costs associated with rendering the machine offline for days or weeks.
If people don't know about the magnet, or don't know that it can't be turned off (or perhaps assume it's "off" because the scan was over, as I would guess happened here), accidents happen.
I thought these days, most MRIs did have an emergency quench button.
So the emergency quench is less useful than it sounds in these situations... it's very likely if an MRI is going to kill you it's going to do it fast enough for it not to be relevant.
Also, twenty pound necklace?
"She said he was wearing a 20lb (9kg) chain with a lock that he used for weight training."
I expect this story to be promoted by people who benefit from sales of x-ray / CT machines though. MRIs and all of their promise for public health could continue to be set back.
Anyway, I’m complaining as someone who personally has turned down recommended medical procedures after checking radiation cancer risk numbers and realizing the radiation risk was being downplayed. When I saw the numbers, to me the cancer risk wasn’t worth it, so I went without a solution to my health problem. Had an MRI been an option, I would have more likely said yes.
Take a look at the Google Street View link someone posted. It's pretty clear this facility -shouldn't- have been able to acquire an MRI machine in the first place.
It also elucidates how such an accident could happen, i.e they clearly don't have the trained staff and protocols necessary given the danger of an MRI machine. It's very likely the poor gentleman didn't understand the immense danger the machine poses.
They are expensive and rare for a reason IMO. Yes it would be great to have more of them but the best place for more of them is within proper hospitals and leveraging economies of scale to share technicians across a fleet of them in a well run facility.
They shouldn't have been, it's a major failure of access control.
> In 2001, a six-year-old boy died of a fractured skull at a New York City medical centre while undergoing an MRI exam after its powerful magnetic force propelled an oxygen tank across the room.
There shouldn't exist any metals in the room (that are not the machine itself), period. The smallest metallic object can fly off like a bullet. Everything and everyone that enters the room should be required to be scanned with a handheld metal detector.
How is that possible ? I would think at the very least the door would be locked.
From quick searches I believe it is a for profit company.

Granted that probably does not matter, but to me, for profit generally means cut costs, even safety costs to maximize profits.
