Magnetic Resonance Imaging Explained 

I absolutely love it when people who are knowledgeable about a subject explain the subject.

Best video about MRI there is...believe me, I searched all over

Man I would love to have such clarity in formulating my own thoughts. Impressive, informative, amazing

He explained so simply I now understand it. Thank you so very much Dr Daniel Bulte.

I visited the Siemens Healthcare factory in Erlangen, Germany as part of our Bachelor's Studies. The amount of cutting-edge engineering and technology that they have in order to manufacture these MRI machines is astonishing. Simply one of the "craziest" technology companies out there.

Hi Dr. Bulte ~ thank you for the clear and concise video explaining how MRI works, this really helped me study for radiology final exam in medical school! All the best from Seattle.

I hope nobody will repeat this demo near the MRI machine.Great video.

I've explained the functioning of an MRI in a basic form since they were first about in 1980, but this really blows that explanation out of the water and expands it way beyond - brilliant!

Superb explanation, thanks. And I love the fact Dr B chooses 'doing calculus' as an example of what he might get a person to do during an fMRI session, not just 'maths' or 'sums'!

I really appreciate how to the point this is. Some people just drag things out and repeat themselves over and over which gets super annoying. Thank you!

Really a clear explanation about the MRI system. The only vedio on youtube which can clear the concept. Thank you sir for your great vedio

Congratulations Dr. D Bulte. Your explanation of MRI is the best I've ever read to date. This sharing of important information is most appreciated. Thank you!

One of the best descriptions I've heard. Thanks you.

Been searching all over the place on how a scanner works. I finally landed here. Now I got it. Great explanation.

Smart man, thanks for making this, gave me some peace of mind.

By far the best video I've seen about MRI, trust me i'm twelve and this is the video that helped me understand this concept

It's been 10 years since this video was posted..Still, it's my favorite

Simplest way one can explain T1 and T2 relaxation. Shukriya (Thanks) Dr Bulte

Wow, really clear explanation, thank you.

Wonderful video. Thank you Dr. Bulte.

Awesome explanation...

That was real good explanation! Loved it

GREAT explanation!

Came to understand what kind of scan I just had in a MRI mashine. Now I'm totally clueless.

Very helpful. Thank you Dr. Bulte.

Perfectly explained! Thank you very much

Thank you. Now I understand a bit more about MRI.

Thank you so much.... very useful... short but full of information!

Wonderful explanation! I feel like I finally understand MRI now!

Great explanation, gonna have to see it a couple more times though.

Aussie? I loved to know how it works, i asked thr operator and she was like ahhh i dont really know. hahaha skilled. Thanks for this mate!

really clear explanation! thanks

Thank you so much! Brilliant explanation!

Best explanation ever. Thank you

Extremely good video, thank you.

You my friend...are a smart cookie. Thanks

Physicist here and this explanation is amazing

Nice Video! quite informative for my A level Physics and chemistry as well

Thanks for the video. Super cool!

Thank you for this video!

This guy is good. Thanks for this video, helped a lot .

Signal in MR images is high or low (bright or dark), depending on the pulse sequence used, and the type of tissue in the image region of interest. The following is a general guide to how tissue appears on T1- or T2- weighted images. Dark on T1-weighted image: increased water, as in edema, tumor, infarction, inflammation, infection, hemorrhage (hyperacute or chronic) low proton density, calcification flow void . Bright on T1-weighted image: fat subacute hemorrhage melanin protein-rich fluid slowly flowing blood paramagnetic substances: gadolinium, manganese, copper calcification (rarely) laminar necrosis of cerebral infarction . Bright on T2-weighted image: increased water, as in edema, tumor, infarction, inflammation, infection, subdural collection methemoglobin (extracellular) in subacute hemorrhage.. .. Dark on T2-weighted image: low proton density, calcification, fibrous tissue paramagnetic substances: deoxyhemoglobin, methemoglobin (intracellular), iron, ferritin, hemosiderin, melanin protein-rich fluid flow void

Thanks! that was very helpful.

great explanation!!! thank you million!

Excellent video!

its 8 years since this was published but thankyou i really needed this for my physics asg lmaoo

Great explanation, I agree.

very well explained!

Very informative, thank you.

amazing explanation!

Very informative thank you.

That is quite fascinating how two interacting (but opposing axis fields) can create a proton spin and thermal spike at that scale.

Great content!

Bravo, majstore!

Good explanation!

Thanks! That was quite helpful

Best explanation on mri

Very good explanation of a very complicated subject, although I wish you would have mentioned more about how gadolinium affects the contrast.

Amazing explanation

You're a life saver

Excellent thank you

I salute you Sir !!

SO helpful thank you sm

That was great. Thanks a lot.

so articulate bro. wish u were my lecturer

Very useful explanation

Brilliant explanation, could do with a little more on hydrogen non zero spin etc, but still the best video I can find

Great!! Thank you

nicely explained

Fascinating

Very informative video

very helpful thank you.

excellent! thank you

thanks so much I finally understand.

I'm here because had 7 within a year due to a Brainstem Cavernoma found on Nov 2017 after having a stroke since it's in my pons doctors do not want to remove it they all say it's too risky I'm 36 yrs old never had any health problems just bad headaches thanks to an MRI doctors were able to diagnose me. For now all I can do it's wait and see since brain surgery it's not an option for me. Over all good video🤗 I kinda of got it

Good job 👍

Amazing

nice explained

Very Helpful! Thank you ^_^

Thank you...

Thanks!

Very Good. I am Looking for some explanation for T1 and T2 imaging. and how does it happen?

its v v v good

Most expedient explanation on MRI..👌...all others will only ever say..3 magnets, an electromagnet, supplying current,...and boom you got the image...like wtf 😒

Hello, I am studying EM-5 Comprehensive Electronics subjects on ac/dc motors. My question is what type of power supply does an MRI machine use? Single-phase or Three-phase? Just curious?

Bravo

amazing stuff, i wonder what they were experimenting to discover this

So articulate

Thanks ;)

mind blown, im here cos i had an MRI scan of my wrist today.. damn

Thanks for the explanation. I'd like to point out that particles are not spinning. Spin is a fundamental quantum property of the proton and has nothing to do with it spinning.

Do you have a phd? You are incredible.

I have new videos here: ru-vid.com/group/PLBJfp4cQ8FWpl-f8y4Vl7yLTTTEBdPmh7

Why was the N removed from the acronym MRI?

I think this would have been better if he’s explaining the concept while lying down on the MRI and on side screen, we can simultaneously see his brain scan (real time)....

I'm not sure if the spin actually process in the transverse plane when RF pulse is applied, as explained from 2:30min. As far as I know, hydrogen can only have two energy states, high or low, and it is the NMV (Net Magnetic Vector) that lies in the transverse plane which gets detected by the reciever coil, NOT the magnetic moment nor the spin themselves.

this guy is smart

That's pretty nuts.

So when you have a magnetic field on and your water particles are processing towards the initial B-field...you then turn on an orthogonal B-field to get the water particles to process towards that one (at a orbital of energy). But dont you have to turn off the orthogonal B-field once the water particles start processing with the orthogonal B-field so that they quickly jump back down a state because they will start processing towards the initial B-field. So once the the orthogonal B-field is turned off and the water particle is processed back to the initial B-field , doesnt the water particle emit a photon (which is light) and then they have a sensor waiting to catch all those photons to get a good image of bones,tissues,etc? emits a photon because of the jumping down from a higher orbital to a lower orbital? or am i thinking of it completely wrong?

Why my Dr. ordered me a CT-Scan. I want an MRI. i dont want to be expose to ionizing radiation please
