Projectile Cases

In this next section we're going to be discussing some of the MRI injury

0:05

risk factors.

0:07

Now many of the most photogenic risks are the ones

0:12

with objects or devices that fly into the magnet.

0:16

This was an accident that occurred just a matter of weeks prior to this

0:20

recording. Uh,

0:22

patient with a mobility assist device for a

0:27

non-weight-bearing foot or ankle surgery.

0:30

The patient was purportedly instructed to simply wait outside the magnet room.

0:34

The technologist stepped away for a minute and the patient thought they were

0:38

being helpful.

0:39

Walking into the room after I shared that first

0:44

image,

0:45

I got a slew of other ones also accidents that had occurred within

0:51

a week or two's timeframe. This is a transport chair.

0:56

This is a wheelchair. Purportedly,

1:01

this particular accident was going to cost seven figures in terms

1:05

of repair to the MR system and downtime.

1:10

So simple accidents can have disproportionately large cost

1:14

consequences. A little difficult to see this. This is grainy.

1:19

This is taken through the control room window.

1:21

So we're seeing the RF screen in the observation window,

1:26

but this appears to me to be an MR.

1:29

Conditional oxygen cylinder that's probably in a

1:34

conventional trolley.

1:36

So the magnet attracted the trolley, if not the cylinder,

1:42

and stuck it to the face of the boar of the magnet.

1:46

This was a syringe pump for the bolus injections

1:51

in ct.

1:54

Somebody brought the CT syringe injector pump into the

1:59

MRI environment with some pretty disastrous results.

2:04

This is a floor cleaner.

2:07

This is an accident in which somebody at the site attached an

2:12

MR conditional infusion pump to an IV pole and brought it into the room.

2:18

Although the IV pole itself was not MR Conditional,

2:23

the photograph here is after the MR conditional pump had been removed.

2:28

And obviously we have a couple of hospital staffers trying desperately

2:33

to keep the IV pole from flying the rest of the way into the magnet.

2:39

Here is a vent brought too close to the MRI scanner.

2:45

I suspect just based on the image that that is a particular

2:49

brand of MR. Conditional vent,

2:52

one of the conditions of its safe use is to be kept

2:57

a certain distance

2:58

Away from the magnet,

3:00

not defined so much by distance as the magnetic field to which the vent

3:05

is exposed. And then if you're interested in a long read,

3:11

this is a story.

3:12

The QR code will take you to an article in which at an

3:17

imaging center that was imaging prisoners transported from the local prison,

3:23

the prisoner was walked into the MRI scanner room

3:28

with the chain around the abdomen and handcuffs on the chain around

3:33

their waist was attracted to the mri and the prisoner was stuck to

3:38

the MRI and in pain and screaming.

3:41

The guard who was guarding the prisoner heard screams,

3:45

didn't know whether those screams were coming from the prisoner or the MRI

3:50

technologist.

3:50

The guard runs into the magnet room with their utility

3:55

belt, including pistols and handcuffs and all of the accoutrement.

4:00

And the guard also gets stuck to the MRI scanner.

4:06

In the beginning of 2023,

4:09

there was a lot of noise made about this

4:13

particular accident. This accident occurred in Brazil,

4:18

but it was an adult man who was escorting his mother

4:23

for her mri.

4:25

And he walks into the magnet room with a pistol and the magnet

4:30

pulls the pistol from its holster or from its concealment,

4:33

and somehow it initiates the pistol to fire around and

4:38

shoots the man in the back or the abdomen.

4:43

And he succumbed to his injuries a couple of weeks after the accident had

4:47

occurred. Now, this accident that we looked at earlier,

4:52

the patient with the mobility assist device.

4:55

So after this scooter gets stuck in the bore of the magnet,

5:01

all of the available staff from this imaging center all gather round to try and

5:05

extract and pull the scooter out of the magnet.

5:10

It is not at all uncommon for feral magnetic objects to

5:15

exert hundreds, perhaps even a thousand times.

5:19

The force that they normally experience due to gravity downward force,

5:24

it is in entirely common for them to experience hundreds if not a thousand

5:29

times the force in the horizontal direction from magnetic attraction.

5:34

So they've got the whole team of techs and staff

5:39

about ready to pull this scooter out of the bore.

5:43

When the patient whose scooter this is asks about getting

5:48

their firearm,

5:50

the patient was an off-duty police officer and in the bag

5:54

at the handle of this

5:56

Scooter was the police officer's firearm. Well, needless to say,

6:01

they stopped trying to pull the scooter out of the MRI at that point and instead

6:06

called for the OEM to ramp the system down.

6:11

And if you want a further example of just how much

6:16

power there is in the magnetic attraction of a feral magnetic object

6:22

you're going to see in this video,

6:24

you're gonna see four adults with a rope pulling

6:29

a pistol off of an MRI scanner. And again,

6:34

the attractive force exerted by an MRI on a

6:39

ferromagnetic object is several hundred,

6:43

perhaps 8,000 times whatever the weight of that object is.

6:48

So a pistol maybe weighs five pounds.

6:53

The force of attraction acting on that pistol towards the MRI

6:58

could potentially be several thousand pounds of force.

7:03

This is another accident that caught the attention of many of us.

7:08

This was an I C U patient who was brought

7:13

down to MRI on a conventional hospital bed.

7:18

And while the MRI technologist turned

7:23

their back for a moment to answer the phone or enter patient

7:28

information into one of the computer systems,

7:32

the nurse who brought the patient down and was presumably MRI

7:37

safety trained,

7:39

brings the hospital bed with the ICU patient on it

7:44

into the MRI scanner room. Now thankfully,

7:47

the ICU patient was just sort of tossed off the

7:52

bed and landed on the floor some bumps and bruises, but otherwise unharmed.

7:57

The nurse on the other hand was not so lucky.

8:01

The nurse initially was actually between the bed and the MRI

8:06

scanner and was pinned with the force of the

8:11

bed being attracted to the MRI scanner.

8:15

And per accounts that I've heard,

8:17

they actually sort of pulled the nurse sideways out from between the bed

8:22

and the MRI scanner.

8:24

The nurse was badly injured as a result of this particular accident.
