They paint that line on the floor for a reason. Anything that gets stuck to the magnet ain't coming off.

There was a case in NY where an off duty cop took his pistol into a MRI Suite and it pulled the gun into the machine and caused it to discharge. Was a 1911 IIRC. Dont know if it was a proper one or one of the screwed up versions where someone redesigned perfection.

The magnet pulled the firing pin forward into the primer once the gun itself couldn't get any closer. |

I remember a case where a nurse or orderly carrying a oxygen tank (I think)entered the room where someone was getting an MRI. The tank got the pulled into the machine and killed the patient.

It's such a powerful magnet it makes the very cells in your body vibrate (well the iron in them anyway), that kind of power is not to be trifled with.

Story of a mobile MRI unit in Playa del Rey, CA (in L A County).
Snotty cop pulls up next to the trailer housing the MRI. Technician warns cop about possible damage to car. Snotty cop blows him off, leaves car for 15 minutes. Car was towed. |

Most of that is non magnetic. I have a large rod in my leg and several screws. MRI is fine, and doesn't set off the detectors at the airport either |

The force of the device's 10-ton magnet is about 30,000 times as powerful as Earth's magnetic field, and 200 times stronger than a common refrigerator magnet. |

A friend of mine had a bullet basically next to his spine, he could feel it moving when he went in one, but it didn't rip it out of his body. The movement of it caused them to take it out immediately though as to not cause anymore nerve damage. |

Generally, if your implant is anchored in bone it is OK to scan. I scan knee and hip replacements routinely looking for issues adjacent to the replacement.
Magnets are usually a no go, but there are some magnetic implants that can still be scanned under certain strict and controlled circumstances. The open scanners are very weak compared to the video, the images suck and most implants manufactured in the past 20 years are fine for a 1.5T conventional machine anyways. |

That's why anyone with service history or who has worked around metal at all gets a few Xrays looked at closely before an MRI. I've had a few MRIs with my orthopedic surgeon, and based on my history he makes me get new Xrays every time just in case we missed something and got lucky the time before. |

You need to go to another facility. Knee replacement and hardware should not disqualify you from having an mri. Heck, there is even special software out the past few years to aid in scanning replacements. |

In the MRI, the magnetic field "holds" the hydrogen atoms, then they are blasted by RF which causes them to flip in the magnetic field, when the RF stops, the hydrogen atoms flip back, and in doing so, emit very specific RF which varies according to the chemical compounds containing the hydrogen.
