Sorry, maybe that explanation would work for scientists and electrical engineers; but for us common lowlife slobs with other Masters degrees, that did not make any sense at all. Any way you can make a video without using technical jargon? Also, animation showing movement of internal parts as they make those sounds would be most helpful. Don't slow the sounds. We've all had to have MRIs at one point or another, so the sounds are very familiar. I've always wondered what makes the different sounds, and unfortunately after your video, I STILL DO!!!

@@Jared7873 It's actually the windings in the gradient tube (gradient coils) that moving/trying to move. The gradient tube is constructed of fiberglass and epoxy. Hundreds of amps of electrical current pulse through the coils at audio frequencies. Something's got to give. In this case, massive amounts of audio frequency "noise" is generated. The gradient coils are water cooled, so that may give you an idea of how much power is used by the system while scanning. Not to mention the radio frequency amplifier, which is part of the system.

There is a cryogenic pump cooling the magnets. That makes most of the noise, it's a helium displacement mechanism ususally driven from a synchronous motor.

Some manufacturers enclose the gradient coils in a vacuum chamber, which greatly reduces the noise they create during a scan. But this comes at a price as the coils can't be cooled as easily. Gradient coils are liquid cooled due to the immense amount of heat they generate during a scan. Old, old MRI magnets, and I mean OLD now, used a separate jacket of liquid nitrogen to insulate the helium vessel to reduce the amount of helium boil off. This necessitated a weekly fill of nitrogen to replenish it. The helium liquid would usually need to be filled approx every 3 weeks. This was in the days before the cold head technology came along. Naturally, those old magnets would not exhibit the pumping noise of a cold head because there wasn't one. Magnets with cold heads theoretically never need to be refilled as the helium boil off was constantly recycled back into the cryo vessel. HUGE amounts of cooling water is needed though to keep the cyro compressor happy otherwise it overheats and shuts down. When that happens helium boil off rates go through the roof. And that stuff ain't cheap.

You can easily imagine being warped or beamed. For the Techno-Fans among us: You will hear some known beats, I am sure. You will know where they are taken from... For me it was an interesting mix of SciFi and a Technoparty. Just consider wearing a thick sweater! It was very cold and windy inside this giant and I wished someone had told me before to wear a heavy sweater. I was happy beeing in this head-thing because it kept the cold wind off my head.

It’d be a lot more zen if I wasn’t being told to hold my breath over and over again. Last MRI I had was about 1.5 hours in the bore. Every itch comes out to torture you, arm is always sitting funny and starts to hurt, need to piss etc but thru it all I’m still as a mummy because I want the best possible result.

As for the shaking, prob a specific pattern of drive to the gradient coils. You’ve got 1-3 Tesla (1000-3000 gauss) electro magnet with these gradient field coils they drive that basically wobble the magnetic field of the electromagnet to make the hydrogen nuclei in the cells of your body spin this way or that and it takes a tremendous amount of current. The coils are well bonded to the housing but the forces are tremendous so they move around. The force is proportional to the magnitude of the current, the dimensions of the loop, and the intensity of the field.

literally just had an MRI scan done about 3 hours ago and it was exactly the same for me as what you described. Except that I was lying on my front so it wasn't that relaxing. But it was mostly quiet (relatively) except for a section at around the middle of the scan when it made very loud clicking / banging sounds, and it also started shaking and vibrating. Pretty interesting nonetheless

I love MRI scanner. Can’t explain that but as soon as I hear their sounds, I feel connected with them. Specially with the breathing sound of the coldhead. I love laying inside a MRI scanner. It feels so cozy. I can totally relax there. Actually more than in my bed. That all is so very strange 🤔🤔🫣

In the early days the MRI technicians called the coldhead the "the heart of the tin man." If the tin man's heart stopped beating it was a major repair.

Opposed to the images in this video, I was always put into the MRI tunnel (coil), head first... and it sounded nothing like the sounds in this video. The very high volume sound that I experienced (every time), was more of a "NONGH-NONGH-NONGH-NONGH" etc., etc., etc. sound.

Not much different reasons than for the 50 or 60hz humming sound a transformer produces. (mentally downshifting to think about the fact that power transformers are a thing of the past in modern household technologies). Not much different reasons than for the high pitched humming sound some switched power supplies produces.

If you're a worried first-timer, here are some tips. It's my experience for brain MRIs. DON'T BE AFRAID, it's not that bad. If you are very nervous you can show up 30 minuted earlier and ask for something to calm down (in swiss hospitals). For me the worst part of getting my brain scan is the dye injection. Once I'm in, I do a mini-meditation: name 3 things your body feels (like your socks touching your feet, whatever is under your fingers,...), 4 things I hear, 5 things I can see. That's 5-10 minutes gone. Then another few minutes appreciating the fact that you get to be lazy and HAVE to do absolutely nothing and it's completely justified! Boom, I'm half way there. Then, rinse and repeat. Or plan my MRI reward. It's usually a good pastry and coffee. Pizza maybe? Anything, really. Got plenty of time to figure it out. Making lists also helps. Top 10s for example. Until finally the tech announces the dye injection, which means there's only 10 minutes left! You can do this! ❤✌️🖖

I just had an abdominal MRI. Even if you never thought of yourself as claustrophobic just answer Yes. This test is 30 min long on your back. Fat people can’t fit in it so yeah it’s tight. Each aspect of the test on its own is not overwhelming but take my word for it. The test will maybe give you a flair up. It’s crazy loud with sounds like spaceships. I got the flight or flight response and I felt like I had been in a major car accident afterwards. Think of the worst amusement park ride ever or going over Niagara Falls in a barrel.

I have acute claustrophobia since a kid. Thank GOD the V.A. have latest equipment & the openings flare out, giving a better experience. I was unlucky enough to get into what looked like a first gen. machine. It was like being in a straw! I was told "If you get stressed or panicky, just squeeze the bulb & it will pulse air to the alarm!" As I was going in, my entire body was squeezed by the sides. I wasn't even fully in & I was pumpin' that little bulb so fast she probably thought I was having a seizure!

The first time I saw an MRI scanner I thought it should be on a James Bond movie set.... complete with playful laser beam! "Do you expect me to talk?". "NO Mr Bond, I expect you to DIE!" Although not claustrophobic myself, I was glad when I was released from the scanner. I could well imagine someone who IS claustrophobic being somewhat alarmed by the experience.
