How does an MRI machine work?

Even after you explained it, I still don't understand it.

Now I understand why they told to take creatinine test before MRI scan

The intelligence that God has given man!

Thank Nasa for the MRi

Its very comprehensible explanation. Thank you.😊

I can't believe the first MRI was invented in 1930. I still can't believe it's available in 2023

very useful video thank you so much

Wow awesome. This video is perfect for students who have spectroscopic techniques and their applications. 🎉😊

Leave a like if you got here because of the "anal rail gun"

Truly Amazing!

Day before : I don't have claustrophobia
Right before getting in: I ACTUALLY HAVE CLAUSTROPHOBIA !
20 minutes in session: I can handle it. It sounds like Daft Punk song.

Terrible device Magnetic resonator. If it changes the spin of the molecule, it can turn the water in the body into poison😱

And also increase chances of

Life..

So basically it works by magic

hands down the best and to the point commentary on the working of MRI.

Having had several MRIs, this is the first time I understand hoy the work

Looks like they have a left posterior cerebral artery infarct

Despite the few oversimplifications- this is one of the best explainer pieces I have seen on it. Yes there are 3D mri scans- there are also interpolation methods as well- but MRI scans are usually single plane. At that point it gets into simantics. The actual physics and operation were explained well!

Now I understand how little I understand MRIs

Thank you!!

Why likes and dislikes are disabled ?
Also, in which universe did you see that we represent oxygen atoms in a O2 molecule in yellow ??

??? this doesn't make sense at all

simply incredible ! I'm currently an RT student considering exploring CT or MRI and learning about MRI just now seems pretty cool !

The MRIs I mostly used are the Tobisha ones. Now it's just semies

So drink plenty of water before an MRI?

I get an MRI every year

The explanation is simple beacuse that was explanation how scan proces works, not how machine works. There is no mantionig about Helium and why is used, about real physics of superconducting. Explain that part to audience please. Explain what happens to every material when it reaches temperatures "near" absolute zero (-273 c) and exposed to magnetic field. People must know why this is so expensive machine, and also that tehnology that stands behind machine is not rocket science, mather of fact, it is an very old tehnologie. But it is very interesting tech, beacuse, it is in a sphere of HyperPhysics, today there are some new materials that are in a state of Superconducting on much higher temperatures, cooled yust with liquid nitrogen (-196 c) ...(relatvly cheap gas).

MRI contains nearly 1700 liters of liquid Helium (Helium cannot be artificially produced), and only Helium costs around 50000 dollars.

B.R.

Crazy!

And what about the loud noises inside the machine?

This sounds like those tutorials that tell you to draw. Step 1: draw a circle. Step 2: Draw the owl. How the information received is translated into an actual 3 dimensional image is basically just ignored.

All came from Quantum Physics.

Very good explanation. This is how one should explain.

Thank you, as a dimensional traveller, I have been searching for answers on how to control my own brain into time traveling or traveling back to my original timeline, before the world started changing on me. I have jumped over 4 times in the past month, it has something to do with ley lines and zodiac signs, combined with magnetic fields around us and our brains.

I would like to compare the sounds made along with what is occurring.

My brain is way too smooth to understand magnetism and chemistry, but I have at least a little better understanding MRIs now! Thank you!!!

Thank you so much ❤❤❤❤

Thanks👏

Well it is extremely inaccurate, how could you even make up something like this. Smh

it's scary.. I wish no human goes into this machine.. it's scary af

I didn’t know that I have a blue arrows flying in my body 😂

Man is awesome.

The contrast dye is toxic. Will cause serious health and mental problems. Do not inject. Warning
MRI Gadolinium Toxicity Support group online. Stay away from this procedure with toxic dye.

Eat monster magnet go into MRI results are you'll be blasted in gibs it's now easy to see you from inside on risk

Very useful

Sorry but this is an explanation so much broken down that it is far to faulty.

this is really clear. Thank you.

The technician didn't tell me the radio waves would increase my body temperature. As soon as she turned the machine on, my body felt warm and I began to panic. I thought if was going to be like this for another 25 minutes I might as well get out now. They give you a panic button to click, but I chose to focus on my breathing and stayed in anyway. The heat sensation came and went a few times. It wasn't too hot in my case, but it was a rather alarming experience without knowing it was coming.
