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

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

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

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

        This isn’t an implant though. Massive difference.

    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. )

      Neodymium magnets?

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

        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.

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

    Metal in a CT machine = bad image

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