Nobody wakes up in the morning and thinks "oh today I'm going to invent an MRI machine". It's all a cumulative process of years upon years of discoveries, testing, and development of technologies that together can be used to create something like this.
You have to study whole 4 years course of biomedical engineering to understand that .. or a 5yrs coirse of nuclear medicine tech. /Radiology/medical imaging tech . Etc. 😂
Step by step,we're just seeing the final result of a bunch of tiny discovers and people going "Oh if I put these 2 together something happens". Someone probably noticed radio-waves through water release energy. Probably wondered then how much/at what frequency. Why is it only some water and not all of it? - Discovered water has their own specific magneticness to them. What if we matched another magnet outside that emits radio-waves and bounced the frequency back? We get a 1 dimensional point of data back. How do we make it 2nd dimensional? Spin it around the object from different angles - in a circle would cover every angle. How do we make it 3d? Take a ton of 2nd dimensional images in a tube and stitch them together. Spinny tube shaped thing with magnets in it that detects water, aka an MRI. This was a rough idea of how I think it may have been discovered/invented. Its not accurate to how it actually was invented, but rather to be like, an example of how ideas come from other ideas, but then all together become something that would seem impossible if not for following that path of puzzles and curiosities.
Is it possible for an MRI machine to be improperly magnetized and cause a patient to have after effects from some kind of increased magnetism of their body?
@@kristenkell5153 An MRI machine goes through a great deal of safety nets before they’re ready for clinical use. I’ve heard of one story where a patient said they felt like their whole body was “spinning” even after the scan. Everyone is different and it’s my job to screen each person before they are even laying on the table.
@@kristenkell5153 Yup, typical symptoms include nausea, dizyness and slight loss of balance. Headache if you work all day around the more powerful ones. But they have no know long lasting efrects FOR NOW (and they probably won't discover some, but you never know for sure)
I have a doubt.... What happens when all hydrogen molecules starts rotating in magnetic field... At that time there will not be any use of radio waves right?.. Then how the image can be formed?
I'm having some residual noise a few days after - not fond of that! But when the clanging is going on I count the patterns: 1-2-3-4-5-6-7-8-9-1-2-3-4-5-6-7-8-9-etc. and it's really helpful. It makes me feel like I"m part of the process.
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!
Are you referring to multiplanar reformation for 3D images? What would be an example of a 3D MRI that does not rely on Fourier transform for 3D modeling?
It's totally worth it, I've worked in all 3 fields and am currently working in MRI. You're a lot more in charge of parameters and image quality in this field out of the three. Enjoy!
Thanks for the explanation! Are the noises this video used for the gradient and the magnet reflective of their real sounds that I hear in the machine? I get 3 MRIs (a perk of multiple sclerosis medication haha) every year so those sounds you used are well-known to me.
The ticking noises are pulses or recordings yes, the buzz noises are the gradient coils and other components slightly deforming under the high power currents required for localization.
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.
I got two mris and didnt feel this either time. Actually... last time it was quite cold in the room and the techs had to retake an image because I was shaking a bit
That feeling is quite unfrequent on adults with nowadays equipment, certainly could happen often in extense scanned areas(such as spinal cord, abdomen vs just knee, foot,etc)or lots of sequences (T1,T2,FLAIR,etc) in order to obtain more and useful images to support your diagnosis
@@mcazares48 It can raise your temperature a couple of degrees. The sensation was that I was getting cooked specifically in the area of the machine's focus during both the lumbar and cervical scans. I meant to ask the tech about this at the end of the appointment, but didn't get to see her. I asked my chiropractor about it instead, and he said it's very uncommon, and that there are several theories as to why it occurs. But no, it's not just panic.

Yeah... You need to learn a lot of things before completely understanding this video. Like. Dipole of a molecular And How electromagnetic waves forms. And How a magnetic dipole interact with a magnetic field..... Mainly these things
This is a bit simplistic. When body placed in magnet, the hydrogen protons precess and have a resulting magnetic field either inphase or antiphase with a small net value inphase with mri field so body is like a bar magnet. The application of rf at the lamor frequency (resonant) frequency would not produce an image without the appllication of gradient pulses which alter the magnetic field in a linear way. The rf puls basically flips the net magnetization 90 degrees, then when the pulse removed, the net magnetisation moves back to inline with magnet field and as it does this, the sigal from the body can be measured.
Sheldon, is that you? I thought your specialty was theoretical physics. Tell Penny I said hello. And cut Leonard a break every once in a while will ya?
@@rafflesxyz4800 im a native English speaker and could still understand it. English is not everyones first language so calm tf down, it aint that deep bro
plz correct me if i am wrong but the gradient magnetic filed produced by AC current (in x, y, and z direction) is so that 3D image can be produced. The entire concept is based on Nuclear Magnetic Resonance, chemists use NMR spectroscopy but we dont use the gradient in x, y, z, because we don't need it. In MRI as far as i remember gradient along one plane (transverse plane )allows to control the thickness of the slice , another to calculate the amplitude of signal at each point in the slice and the gradient in the last orthogonal plane the phase. so the thing that was said about the brain , the lungs etc is not really precise as the image is made of many very thin slices.
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.
Uh--they work to get images of the HARD tissue as well. They're so comforting--they give you earplugs and headphones and with the patterns of sound and the nice blanket and socks they provide, don't be surprised if you fall asleep (I have)!
I had my vision become blurry but I guess it's because you have to lay still the whole time staring at nothing. What I didn't enjoy was the spasms in my legs tho.
D Kahn my scan was for my shoulder and I didnt feel anything out of the ordinary afterwards. I did notice my ears a little faded because of the loud noises. But i was safe to drive and everything afterwards. Im sure some water and a good meal before would keep you from being dizzy👍🤝
High level - the machine focuses on different areas in the body and reads out the effect from changing energy levels in water molecules in that area after they were proactively energized. This is mapped to the 3d image / slice in the body via software.
Was feeling very anxious for my MRI tomorrow, for a brain tumor and some other… kinda small tumors/bubbles/idk what they are around my body. This helped me calm down a bit,
@@kushalparekh1017 Well, as someone super sensitive to noise I asked to be able to wear both the ear plugs and the headphones though I'm not sure if you'll have both choices. After that, for me as an audiophile? I *LOVED* it. I heard the entire thing as sequences of music, like if you could record all the noises and section them you could make some amazing music. I kept my eyes closed most of the time but I also don't have any issues with enclosed spaces. Either way if you love music I recon that if you just close your eyes and concentrate on all the rhythms you'll be okay; you might even enjoy the process! A lot of people do! For me it was relaxing. **Tips** (with explanations; for TLDR, skip to bottom.) *Clothes!* To make things simple if you don't want to have to change into their gowns, go in wearing clothes that don't have any metal on/in them like sweats, workout pants, a bra with no underwire if you're female, etc. *Jewelry!* If you have any jewelry/piercings you should take them off/out to be safe. (I know my case is rare but since it exists I figure I'll just leave this here.) If you can't take out/off the jewelry for whatever reason I suggest either going to a store and testing out your jewelry (through your clothes if you must) for magnetism because if they don't magnetize with a strong magnet you should be fine to keep them in for the MRI but otherwise, or just to be safe, just go in without any jewelry if you can, even if you have to get someone else to remove them or use toothpicks or nonmagnetic jewelry to replace them with. (My nose ring wouldn't unscrew so I had to grab a magnet haha but it turned out fine. Just do what you can and communicate with your technician if you can't get any jewelry out. They'll have options for you.) You can also ask for your results on a disk in most places if you want (though I have NO idea how to read mine it might be good to have a personal copy). And if they don't find anything reason and they don't off you a contrast for whatever reason ask them if an "MRI with contrast" might be helpful to you. I know nothing about this field other than it exists so I might just be saying unnecessary things, now. **TLDR/Conclusion** *But I can't think of anything else! I loved it! Wear non-metal clothes/jewelry for a simple in and out without having to change, close your eyes and enjoy the music!*
@@kushalparekh1017 Nope! :) Though I suggest that if you're prone to passing out you eat something. If you're nervous, I also wouldn't eat anything that would get your nerves even more worked up like sugar or caffeine. If you're the nauseous-nervous type I'm not sure how to advise.

I was recommended by my ortho surgeon to undergo an MRI. My question is I have a piece of iron inside one of my tooth as a result of dental root canal. The iron however is covered by a porcelain crown. Can I take the MRI procedure?
I feel like the video's explanation kind of yadda yadda's the link between the energy release from low-energy water molecules and the imaging software.
So when you make a MRI appointment do you need a reason like when they ask why do need one if you when to a orthopaedic doctor like do you say my orthopaedic wants one or what?

This is a bit simplistic. When body placed in magnet, the hydrogen protons precess and have a resulting magnetic field either inphase or antiphase with a small net value inphase with mri field so body is like a bar magnet. The application of rf at the lamor frequency (resonant) frequency would not produce an image without the appllication of gradient pulses which alter the magnetic field in a linear way. The rf puls basically flips the net magnetization 90 degrees, then when the pulse removed, the net magnetisation moves back to inline with magnet field and as it does this, the sigal from the body can be measured.
