A little metal wont kill you. It will ruin the image.

[–] thethrilloftime69@feddit.online 28 points 6 hours ago (2 children)

Metal will ruin a CT scan. Metal will kill you in an MRI machine.

But that's zinc shot... It doesn't even look like steel. It shouldn't be attracted to a magnet. Perhaps they're steel inside, but the outside is clearly zinc.

Isn't that just because they use non-magnetic metals for implants?

[–] gens@programming.dev 7 points 5 hours ago

Titanium, afaik

And that's zinc shot. Perhaps they're steel inside, but the outside is clearly zinc.

In general, metallic orthopedic implants are not affected by MRI. 

This isn't an implant though. Massive difference.

[–] toynbee@lemmy.world 2 points 4 hours ago

I soon expect to have screws implanted in my spine. I also have other infirmities. I hope like hell to never have screws ripped through my vertebrae by an MRI.

[–] MehBlah@lemmy.world -4 points 5 hours ago

What are implants made of? Stainless for the most part.

[–] MatSeFi@lemmy.liebeleu.de 12 points 7 hours ago (3 children)

I think its not about the property of beeing a metall ist a bout beeing ferromagnetic (In that case probably not an issue because these bearing balls are usually out of some kind stainless steel. )

[–] wolframhydroxide@sh.itjust.works -1 points 3 hours ago* (last edited 3 hours ago)

These aren't bearing balls. They're zinc shot. Perhaps they're steel inside, but the outside is clearly zinc.

[–] Thedogdrinkscoffee@lemmy.ca 1 points 6 hours ago

Neodymium magnets?

[–] MehBlah@lemmy.world 1 points 7 hours ago (2 children)

I was told metal interferes with the scan. By a guy doing the scan.

[–] dylanmorgan@slrpnk.net 10 points 6 hours ago (1 children)

I was told that because I have stents (plastic coated with platinum) I can never get an MRI again by my cardiologist.

A friend who makes knives felt the little bits of metal that he’s picked up in his skin over years of grinding blades getting pulled out of him during an MRI.

Maybe aluminum foil in your pocket would only “interfere with the scan,” but those magnets are powerful enough to make any metal in your body come out, violently.

[–] MehBlah@lemmy.world 2 points 6 hours ago (2 children)

I know someone with metal pins in their leg and they have had a MRI. It depends on the metal. Since I didn't specify what kind of metal everyone rushes forward to speculate on how wrong I am.

[–] wonderingwanderer@sopuli.xyz 2 points 3 hours ago (1 children)

The post is obviously insinuating that these are iron balls, so in this context you are wrong.

[–] wolframhydroxide@sh.itjust.works 0 points 3 hours ago* (last edited 3 hours ago)

Except that they're clearly zinc shot. I think the poster made a funny without realising that they aren't steel, unless it's zinc-coated

[–] dylanmorgan@slrpnk.net 2 points 4 hours ago

MRIs work because strong enough magnetic fields will interact with any material, not just ferrous metals. This can be impacted by the structure said materials form (stents are a weave like a finger trap and therefore more prone to interaction with magnetic fields than say a solid cylinder) but I’d be inclined to say your friend was lucky. Ball bearings like in the OP are nearly always steel outside of specific high end applications and therefore would behave like they were coming out of a shotgun shell.

[–] MatSeFi@lemmy.liebeleu.de 1 points 7 hours ago

Yes Metals in general shild RF-Waves used to sample the image (and could get hot by that process)

[–] kersploosh@sh.itjust.works 8 points 6 hours ago

Metal in a CT machine = bad image

Metal (particularly ferromagnetic metal) in an MRI machine = injured patient

Without any milk? Hardcore

[–] BlackLodgeCooper@lemmy.ml 6 points 6 hours ago* (last edited 5 hours ago) (1 children)

You add your milk before the ball bearings? Wtf is wrong with you?

[–] Bazell@lemmy.zip 3 points 6 hours ago

Not everyone likes industrial grease for breakfast, I guess.

[–] RememberTheApollo_@lemmy.world 5 points 6 hours ago (2 children)

I wonder if that would actually do damage. I think it would be painful at least.

[–] salvaria@lemmy.blahaj.zone 6 points 5 hours ago (2 children)
[–] mrgoosmoos@lemmy.ca 2 points 2 hours ago

hopefully the company that advertised it as 100% silicone is sued into oblivion and folds and the people responsible suffer real consequences

I fucking hate false advertising.

[–] RememberTheApollo_@lemmy.world 8 points 4 hours ago

Omg… except I call bullshit on the “speed of sound” claim. That would have been the equivalent of being hit by a 30mm round at 700 mph. That person would have been killed immediately.

[–] GreenKnight23@lemmy.world 2 points 5 hours ago

to you? yes.

to the MRI? probably not.
