Comment on Small little shenanigans

  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.

    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.

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

        Its important to you I be wrong. How powerless you must be in your day to day life.

        Except that they’re clearly zinc shot. I think the poster made a funny without realising that they aren’t steel.

      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.

        Nothing you are going to type here is going to change the comments made by the tech operating the imaging system while I’m testing network connections right next to him around fifteen years ago.

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