This has been floating around the internet.


The issue is the metal, and more specifically, ferromagnetic metal core.

MRI machines use an alternating magnetic field to polarize the water molecules in your body.

When they do, they give of radio waves.

An MRI has a field strength of about 15,000 gauss.  Compare that to the magnetic field strength of the earth, which is about 0.5 gauss.

Anything ferromagnetic will get pulled into the center of the MRI and then the alternating field will induction heat it to red hot almost instantly.

This is why all medical implants, stutre needles, and hypodermic needles are non-ferromagnetic, usually austenitic stainless steel, titanium alloys, or cobalt chrome (Stellite) alloys.

That way, if you have one inside of you and you need an MRI, it won’t turn into a red hot bullet in your flesh.

Where people get into trouble is accidentally having metal on them.  I’ve seen this with machinists who have chips on their body.

This person, I gather, didn’t know his butt plug had a ferromagnetic core.  Had the butt plug been actually 100% silicone rubber, he would have been fine.

The radiologist who wondered what the fuck was up his ass would have emotional damage, but that’s neither here nor there.

That’s my expert witness testimony on this matter.

  1. Years ago, I needed to have an MRI done. Stripped down, but wasn’t willing to leave my wallet in the unsecured locker where I had my clothes.

    No issues in the MRI.

    On the other hand, I had to replace all my credit cards and bank cards. MRI machine erased them.

    1. One of the advantages of chipped cards. A strong enough alternating field can still blitz them, but it’s much hardier than the stripe.

  2. “…anal rail gun…”
    *Eyeroll* No. No, it isn’t. If anything, it’s much more akin to a mass driver.
    These people just can’t get *anything* right when it comes to guns or related concepts.
    And now I’m off to find some brain bleach…

  3. of all the items I never expected to hear anal rail gun was probably up there. But now that someone put that out in to the universe I am sure some movie studio is working on a script. A24 or Grindhouse maybe

Only one rule: Don't be a dick.
