How does MRI work

A basic description of how does the MRI work, no quantum physics, no rocket science. this is for anybody

[@thekeithchannel]

This is the most annoying way to teach something

[@maheswaranponnuraman8790]

Keith Richards y is it so?

[@lindavito3465]

Finally a video that isn`t too deep but helps you understand the main concept. I thought the analogy with car was good. Don`t listen to all those narrow minded people commenting. The video was awesome. Finally understood what all those coils are for. I liked how you made this video step by step by getting into deeper physics. I really don`t get why people commenting here are so hateful, they must be stressing out because of school work and leaving their anger here in YT.

[@marutimukul9414]

A big thanks to this organization!! I'm learning through your efforts!! Thankyou...

[@bluespike1482]

I understand you want to make it less complicated, but it's not quite simplified this way. Don't try to mix up MRI and BMW. They are quite different

[@bepositive2452]

Excellent analogy, Sir!! The best of both worlds ❤

[@MissCatherine1100]

Dear Mr. Haroun, Thanks! That was an elegant, simple explanation. Just what I need right now as a CT Tech about to go on a job interview which would involve MRI cross-training. I truly appreciate your effort!

[@debashishsarkar2679]

I study physics. while trying to understand how does MRI works I had few questions like how to pinpoint location, why RF is needed, why is it called resonant... this video answered all those questions. thanks. seems like most people got stuck at "fist"

[@romyjugroo4542]

I guess anybody can make an electromagnet with an AA battery,a nail and some electric wires,but the MRI machine is a masterpiece of science and technology,which took quite a few years in its development.It is much more than rocket science,in my opinion.Great video.

[@khalood1111]

cyclotron angular frequency (Wc) = eB/m , where B is the magnetic field strength ,mass of proton (m) = 1.67*10^-27 and charge( e) = 1.6*10^-19, when divided they give 95 *10^6 and then divide by 2*pi to get the frequency which gives 15.24*10^6 which is not 42*10^6 as stated in the video. Regards

[@everteq]

no sound?

[@amingorji5876]

Nice and simple explanation! better than any of my professors.

[@r2kordmaa]

There is a difference between simplification and oversimplification

[@ajskilton]

r2kordmaa true so watch what you need to

[@gretawilliams8799]

r2kordmaa There wasn't any but i found after this video

[@kirolloswilson3562]

great effort ...realy very simple thanks Eng/ Mohamed haroun

[@muditjauhri9779]

Superb. We all need more on this topic

[@keerthic6925]

What about electrons In Hydrogen electrons are unpaired. Whether it align in the direction of magneticfield???

[@Jacobvb11]

this was pretty stupid not gonna lie. First he is like look, it's simple just turn the car on and then he's like PHOTON 63gHz

[@6mo75r6y]

i got one point that powerpoint slides converts to be a video is a bad idea

[@rd0769]

from early 1900s silent movie's director.

[@khalood1111]

You didn't explain how imaging happens though

[@phuongminhngo7470]

I have not known how to drive a care yet...

[@eltiarribero]

That was pretty good. Even me, a Mri Technologist, understood that. 😉 😜 😜

[@gretawilliams8799]

I learned to drive a car watching this.

[@toejoe4911]

sure, no rocket science only quantum physics

[@sriharisha251]

it would have been a lot better of you opened your mouth n explained sir. no disrespect. salute to your efforts.

[@salvatoreshiggerino6810]

What's the matter? Cat got your tongue?

[@workwebnet]

Very good

[@dominikak7608]

I was glad for the oversimplification but I would need to explain the RF part again...

[@chloeblack9641]

i understood it perfectly great job.

[@NinoM4sterChannel]

it just got me even more confused...

[@charlierice7214]

using three components of driving to explain this was really poor, now i need to go watch more videos to understand anything

[@waylander2]

Damn can this video go any slower. Wake me up when its done.

[@rukmani6411]

help full video

[@dashakavka111]

spelling mistakes tend to discredit

[@tcd3180]

@00.20 they use a FIST????

[@IramRolon]

Thanks You, This tutorial, it's simple but complete and easy to understand

[@ajgubi19]

But fist..

[@dacoda6668]

This is actually rocket science! it's a very expensive piece of equipment!

[@dual7779]

"The inside is very simple. Using big magnet to get an image." Yet the device costs nearly a million.

[@mrwideboy]

Its because the there is 20Km Niobium-Titanium superconducting wire and at $2 per meter. Its also takes 2 - 3000L of liquid helium to cool them down which is about $14 per litre, then magnet has to be made from highly non magnetic steel, it also uses 5Kw Radio amplifiers, and gradient amplifiers which generate 500Amps in 100uS. all of which are expensive. Its not simple not cheap to get quality images

[@angellaede3852]

De-gas the unit and it's big dollars, that's why the machines are left on. Turn it off and bye bye gas. We were warned by our lecturer at uni about making that mistake.

[@gerardosoriano5057]

Very good tutorial

[@hmmm328]

interesting approach

[@amitbhalerao728]

very good

[@quarter_moon_and_a_guitar]

excellent

[@bfurl69]

Too long. I'm not a fan of explanations accomplished by example. Give me the info and if I don't understand, add an example or metaphor. 3 stars

[@doctorlingo3621]

Great effort, thanks and never mind haters 🌚

[@VinayGuptaBEC]

Well the Analogy wasn't that great; but yeah the concept explanation has been great. Thanks for creating the video (y)

[@TheElderOne28]

good but not complete. doesn't explain how the T1,T2,Flair ponderations are obtained.

[@AyaMohamed-jl3ti]

Well done!

[@jannatulferdousjannat3378]

thanks

[@maggiekickliter713]

hi i

[@jesterchase11]

"but fist".

[@willchen2k]

i hit stop button as soon as i saw " but FIST ". com'on, if you can't even spell check...

[@1mustangsally]

My dad had an MRI and he has a bad back so he asked for a pillow under it and the tech said it would ruin the image? Is that true? Because my dad is 91 and the doctor told him to ask for a pillow

[@YvenelC]

1mustangsally the further his back was away from the coil (the receptor that he was laying on) the grainier the image comes out....for the best images the part has to be right against the coil, the pillow would added to much distance between his back and the coil

[@1mustangsally]

Yvenel Cheriscar Thank you for explaining.

[@JohnSmith-qb5bl]

+1mustangsally I'm not expert, but the pillow might shrink the longer he lays on it. That seems like it would change the location of his body and mess up the image.

[@sapnarahim9311]

Nice

[@robbiepearson4775]

so f....ing slow and no audio.... jesus christ !!!!!!!!!!

[@SlavicUnionGaming]

so much math such wow doge

[@marinacitronova8604]

My brain simply needs MRI cause I cannot absorb such "simple" infos .. ok, i am down with that i will never be left hemisphere dominant person :) Turn for you, guys! I only appreciate

[@ramangrewal2500]

If it's so simple, go and manufacture your own MRI , sell it with free car....lol,,,,

[@antonwebb6942]

I'm scheduled for MRI nxwk n im still not sure it works n done seen a few videos but oh well..

[@0lone0wolf0]

This is a fucken article not a video

[@jayashankarmerla4012]

Somebody should talk or something

[@СерафимСеменов-ф8п]

great video! do not listen to anyone, this is a really good presentation!

[@premkumarsbz3230]

ok

[@OumieAisha]

Science coursework. Thanks!

[@BeatSyncBytes]

Not bad!

[@ajskilton]

thank you for this :O)

[@leannarose8]

this was not helpful whatsoever

[@akskhurana9353]

I want my time back

[@Pamela777Carlita]

Very good !! Thank you!!! you save my but.

[@beardeddad7555]

rocket engine theory is far better than this ;[

[@bellakatherman1477]

I literally understand nothing here
