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

      Titanium, afaik

        How on earth can you tell the difference between steel and zinc at a glance?

        I know it’s my name, but I have to congratulate you on the excellent pedantry!

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

    This isn’t an implant though. Massive difference.

      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.

        Implants are non-magnetic. Wrecks the image, though.

        Ugh, yeah, how do they even do MRIs for people with metal parts?

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

        Usually titanium, but yeah sometimes medical stainless steel. Both are non-ferromagnetic, especially titanium. These balls look like they could well be normal steel or any other metal. Also, implants - unlike these metal balls - are usually screwed firmly into your bones. So yeah, implants should be mostly fine on MRI. Loose balls of dubious metal? Wouldn’t advise it. Keep in mind MRIs are literally powerful enough that metals in tattoo ink can even be an issue - which the article you linked mentions itself.

  But that’s zinc shot… It doesn’t even look like steel. It shouldn’t be attracted to a magnet.
