The issue here is that the company that made the sex toy was likely lying about the material. Implant-grade stainless steel is 316LVM ASTM F-138; it's non-magnetic, and will not be heated up by a strong magnetic field. Cheap grades of stainless, esp. the 440-series, are magnetic. If a company lied about the material--e.g., a hard chrome plating over a cheap, low-carbon steel base--that could cause serious injury. And I've seen exactly that with body jewelry before, so I know for certain that it happens. Esp. since there aren't a lot of health and safety regulations on either sex toys or body jewelry in the US.
Ok, I'm pretty sex-positive, but why risk it at all and wear a buttplug to an MRI? Or at least mention it when asked if you're wearing anything metal?
This is a wild-ass guess based on my limited involvement in the kink scenes in the past.
Part of the sexual thrill of wearables is that other people don't know that you're wearing them. If you've been assured that the metal is safe--non-ferritic--then you would reasonably believe that it would be safe. Alternatively, there can be some mild shame involved, where you get a thrill out of having a buttplug, but also don't feel comfortable revealing it even when it's medically necessary.
Personally, I've been very, very up front with medical personnel with the jewelry I've got when it comes to MRIs and surgery. Many years ago I got a lot of pushback because it wasn't widely understood that non-ferritic metals were safe in MRIs, or that piercings were a very low risk in surgery. These days, there's much less of that; you now have to sign paperwork acknowledging the risks, and that's about it most of the time. But even if I was very very sure about the materials in a buttplug, I'd remove it mostly because it can be removed easily, in the same way I can easily remove and replace the jewelry that I wear in my septum and ears.
Is this the same case that had "anal rail gun" in the lawsuit against the butt plug manufacturer, and gave us this image?
Does it just become really hot or?
Depends on the metal that was inside. If it is ferromagnetic then you get fucked. If not, it is something like brass and you have your own private multi kilowatt heater.
Think it woud be assfucked in this case
There is a reason why the request "remove all metal items you may have on you" is done before starting the exam.
I've seen people with old teeth fillings being rejected because the machine can pull it straight out of your mouth.

Yikes! So, like, what if an MRI is medically necessary for those people? Do they have to schedule a dental appointment first to remove/replace those fillings? Genuinely curious now that you've mentioned that because fillings were not something I ever thought about with regard to MRI safety.
Remember those black filling pastes dentists used to use? Some had metal in it. Modern ones are safe, as those materials were phased out, deemed unsafe. Most stable countries have done this but in some parts of the world it is still possible to have those older fillings in use.
And, yes, I've seen people strongly avised to have their cavities reviewed before undergoing MRI exams. The metalic filling are, according to what I was explained, dangerous by two different reasons: the filling can be physically pulled from the teeth, causing severe trauma, but the metal can heat up inside the mouth and cause severe burns.
Serious question: are butt plugs ever prescribed to elderly folks with incontinence?
I'd much rather wear a butt plug then a diaper.
No you don't. Prolonged dilation damages your sphincter and makes the problem significantly worse. And since that's the same muscle that also controls you peeing, you'll get urinary incontinence too. Overall a bad idea. For these reasons you should never use a plug for long (less than 2 hours) and not too often. There are kegel exercises that help prevent damages that should be done when doing anything anal in general
Call me crazy but maybe these MRI clinics should have walk thru metal detectors installed. Schools have them now, why wouldn't they?
Fun fact: Lots of metals aren't detected by those. I have a single piece of body jewelry that weighs over half a pound, and it's never been picked up by either walk-thru or hand wand metal detectors. Maybe they set the sensitivity too low, but even airports have missed that piece of jewelry (prior to back-scatter x-rays, etc.). I've worn it through two MRIs, along with all of my other piercings, and had zero problems.
Maybe it's not a metal that's ferrous?
As far as my own body jewelry goes, that's 100% it.
(And, if you want to be paranoid, just think: non-ferrous metals aren't going to show up on airport metal detectors either. Nor do ceramics, although ceramic metal matrices do. They'll show up on x-rays, but last I knew you could opt out of x-rays, and the pat down that the TSA does is NOT as thorough as they think it is.)
Metal detectors? Are you serious? It's not like people are carrying guns in there. Oh wait...
Don't they? The few MRI machines I've seen do at the entrance to avoid this shit
Metal detectors aren't ceryycheap but MRI machines are so grossly expensive that the cost of the metal detectors is pennies on the dollar
I had an MRI a few months back with no metal detector before.
Aren't metal detectors like... very cheap, actually? At least the sort of tech they use in handheld ones is somewhat inexpensive as you can get hobbyist metal detectors for the ground for like 40 euros, new. Ofc there's also pro model going for like 600e or more.
My point here being that a very rudimentary one should do the trick in thick case.
Although people really should know whether they have any metal on them, but accidents happen, people forget and do dumb things. A little noise would be beneficial to let people know about the metal — accidental or not.
A metal detector port with (why not?) a gate in front of it that refuses to open in case metal is detected really is still chump change compared to an MRI machine
I thought as much too.
Staff incompetence, probably?
I'm thinking more:
"If they don't disclose ferrous metal and it breaks them, it's on them. If it breaks our stuff, it's still on them to pay us for the damages."
well people don't always get MRIs when they're at their best, mentally
hope she's all right with no lasting damage
And this is why they ask you those weirdly specific questions, as well as do the metal detector.
I am all for kinky shit but if i have something serious like an MRI scan, the last thing i have on my mind is something up my ass 😐
