MRI Safety Tip (Never Do This During an MRI Scan)

MRI Safety Tip (Never Do This During an MRI Scan). In this video we will be discussing an aspect of MRI scan safety that no one is talking about. So let’s get right into it.

MRI scanners require precise anatomical placement into a near perfect magnetic field environment to produce crisp, clear images of the anatomy. This is accomplished by using a laser crosshair assembly to mark the precise location of the anatomical region of interest on the patient. The laser crosshair assembly is calibrated to a known distance from the magnet isocenter so that when the MRI scan procedure begins, the patient transport assembly can move the patient into the exact position needed inside the MRI scanner. So what is the MRI safety concern during this process? It is important to remember that MRI scanners use class 2 LASER assemblies for precision landmark points such as the nasion and sternal notch. During the landmark process, patients may cross the path of the laser beam. It is important to never stare into the laser beam. Class 2 lasers emit a visible light wave that is less than 1 mW in power . They are classified as “safe for unintentional exposure for less than ¼ of a second.” Class 2 lasers do not pose a skin burn or materials burn hazard but they can cause temporary blindness, damage to the retina or damage to the cornea. It is best practice to keep your eyes closed during the landmark process to eliminate the risk of accidental laser exposure. Subscribe to our channel to stay up to date on the latest radiology tips.

I’ve always wondered why they don’t supply patients with the type of eyewear one wears in a tanning bed, to avoid looking at the laser which is usually out of boredom since there’s nothing else to look at

[kiwiboy]

when i had the MRI of my brain, i kept my eyes closed when the laser alignment assembly was used, so no problems !

[MRIPETCTSupportEngineer]

I hope this video was helpful! Thank you for watching.

I’m going for an mri tomorrow. I’m gonna wear my armor suit made of iron and steel. Is that a good idea? 😂 just kidding. I would love to get an mri it’s so relaxing I could fall asleep in their. I wish I didn’t need a dr appointment for one like a walk in would be nice 😂

[jessicah]

CT scanners have this too. I just close my eyes during imaging tests.

I’ve had open heart surgery and don’t know if there are any metal clips in my body or what would happen with the sternal wire which remains in my body.

"I want a GE 1.5T MRI scanner and a Daisy Red Ryder BB gun!"
"You can't have an MRI kid, you'll put your eye out!"

What do you do if your nose or eye starts to itch? I mean an itch that, if you can't scratch it will just about drive you crazy? I get those it seems especially if I can't scratch for some reason due to grease or something on my hands, which tells me I must scratch unconsiously all the other times and don't realize it. I'm not being flippant, I am just wondering.

@MRIPETCTSOURCE What about with CT scans? Is there a similar laser to avoid on those? I have done a few CT scans and observed the laser, but the personal responsible never warned me about the laser, so I assume they think its safe to look at it?

Those lasers aren't strong enough to burn your retinas instantly, your blink reflex is fast enough you'd be just fine.

[theseventh]

Do not cross your arms or legs.
Don't look into the laser.

[mmyers]

I always made my patients close their eyes, besides if the patient is positioned properly, in the coil, the centering point is no where near the eyes, and the laser should be switched off before sending the patient into the scanner.

[carolinejayes]

Eyes closed, keep very still, lots of patience mine was very Loud even with ear plugs in.!

[caroldawson]

I had nothing a sandbag on my shoulder n arm for shoulder damage n non movement it was soo loud I breathed to fast n was told to slow breathing right down as machine can't take pics they will be blrry 2 hrs n a bit in this thing was soo uncomfortable no moving at all n my head felt like brick sitting on it when I came out I was dizzy too.

[BengalsOfRidanos]

What is the point of having loud music on this video and talking as a lower volume?

[germanmri]

Dont do Jumping Jacks while examination.😝 Nice Vid. Lasers are not Good for our eyes.

[JanieDee-xp]

Why is that head cage so terrifying? Could you get out of that thing on your own if you wanted to?

[WalturdTheCat]

My metal dental work was being pulled throughout the whole procedure. I was starting to totally freak out.

[baronvonbatz]

Yeah I won’t look at the laser oh wait I am asleep 😴 during MRI and what got me thinking 🤔 I am awake when I go in the MRI room but somehow I quickly go to sleep……… is it the IV Shot that made me go to sleep during MRI and Surgery

[eli]

i only had the chance to look at it for like 2 seconds(one during entry and the other during exit)
