Just an interesting technical note that I had not seen before. I thought it would be of interest to the banglist.

A number of years ago a not-so-bright patient transporter brought a patient on a stretcher into the MRI suite, oxygen tank in tow. The tank went flying missing the patient’s head by millimeters, crashing into the magnet, detroying the plastic housing and severing some electrical connections. It cost a pretty penny to repair, and we were down for weeks.

Sounds like the officer is not smart enough to carry a weapon.

Phew! Never would happen to me. I carry a Glock...nyuk,nyuk,nyuk. OK, an admittedly cheap shot at all you 1911 guys. Sorry.

Just out of curiosity, why aren’t there metal detectors set up near the entrances to these machines? Just as a precaution should someone forget.

Seems like a common sense measure to prevent such items from getting close enough to the magnetic field to be a threat.

I went in for my first MRI, many years ago, having never heard of MRI before, wearing steel toed work boots. the technician told me to empty my pockets and pretty much did not ask me if I had any metal on me.

I went in feet first and of course the inevitable happened, as I approached the loop my feet shot up and locked to the roof of the MRI-

at that point the tech untied my shoes and my feet slipped out. he then spent quite a while removing my shoes from the MRI machine.

I can't even remember how many MRI's I have gotten. I'm asked at least 5x if there is any metal on or in my body each scan.

Years ago I worked in metal shops and that is a big concern. Seems people with metal splinters in their eyes make a big mess in there sometimes.

stupid idiiot cop and stupid idiot medical crew, any chance of residual magnetism would grab anything metallic, especially that close to the machine!

A 1911 should not fire unless the thumb safety is off and the grip safety depressed prior to squeezing the trigger. Unless the MRI unit released these safeties, or the gun was in an unsafe condition; either worn parts or kept unlocked with the hammer down on a chambered round, or a combination of both, I don’t see how this could happen.

n 2001, Michael Colombini, 6, was killed while undergoing an MRI when an oxygen tank flew out of the hands of an anesthesiologist toward the machine, hitting him in the head.

In 2003, a New Mexico woman sued a Los Alamos hospital, claiming the magnetic pull of an MRI caused an oxygen tank to hit her in the back.

In 1992, a 74-year-old woman hemorrhaged and died after an aneurysm clip in her brain shifted while she was on a table preparing for an MRI.

OK, admittedly one of the few incidents where a handgun got up on its own and tried to shoot somebody. ;-)

I call it a BS story.

ALL Colt 1991 1911's have the Series 80 firing pin safety pictured in red below.

The firearm cannot fire unless the trigger is pulled, the grip safety engaged to ALLOW the trigger to move, and the manual safety off.

Colt went through a HUGE liability case and this 'modification' to the design was the result.

Regardless of the firearm mechanics, safety on or off, an internal spark, caused by eddy currents generated by flying metal through that strong of a magnetic field and igniting the gunpowder within the round would cause me concern. Nothing explosive, especially surrounded by any type of conductor, should be near an MRI.

I’ve got a stent and a titanium/ceramic aortic valve. Both supposed to be non-magnetic.

Not sure if that prevents my having an MRI or not.

I’ve worked in the vicinity of machines but never closer than approx 15’-20’.

The officer notified the technologist that he was carrying the weapon before entering the MR dressing room. The technologist told the officer to take the gun with him.

Another example of the ongoing degradation of English language skills by our so-called educational system. The correct term for someone who operates technical equipment is "technician". Sheesh...

Once the officer was inside the MR suite, the gun was pulled from his hand as he attempted to place the gun on top of a cabinet 3 ft (0.9 m) away from the magnet bore. The gun was immediately pulled into the bore, where it struck the left side and spontaneously discharged a round into the wall of the room at the rear of the magnet. Fortunately, no one was injured.

Stupid cop. MRI = MAGNETIC .... what's in a pistol? METAL.

This isn't a spontaneous firing; this is a negligent discharge from someone too stupid to realize that you don't bring ferrous metals anywhere near a running MRI.

Ah, yes. I once worked for a biotech company who rented lab space in a medical building. We were fine until we started losing data from some of the workstations, and mysteriously the backup tapes (in the same room) were wiped as well. So my partner and I were in there scratching our heads over the whole thing when she says “Holy stuff, lookathat!” or something close to it. There were three paperclips stuck to the wall. Somebody had rented the space next door and installed an MRI machine. Dangedest thing we ever saw.
