MRIs Are Insane

Do you know how an MRI works? It’s CRAZY. It’s not like an x-ray at all. An x-ray is a “shadow picture” - like a hand in front of a flashlight, but for your bones. But an MRI is a “water map” made by radio emissions FROM YOUR BODY…

I interviewed one of the inventors of the modern MRI, and here’s how he explained it.

The concept was discovered by astrophysicists. Don't ever let anyone convince you that pure science is a waste of money.

Also the fact that MRI does not expose you to high degree of radiation like X ray or CT Scan is a big W

I love how enthusiastic and excited she is about all of what she’s talking about! She seems genuinely interested and I’m also learning so much!

I had an MRI recently when I had a tumour growing in the side of my neck towards the side of my face. I requested the imagery and the hospital supplied the slices plus a cool Java viewer to scrub through them. It's crazy being able to look through your own head and see your brain, bone structure, eyes, muscles etc. As an engineer I found it utterly fascinating.

I had an MRI a few years ago. While the tech was setting everything up, I was asking questions about its operation, and they were explaining everything to me. I have a background in the medical field, and am a bit of a tech geek, and still couldn't help but feel the machine had a hint of magic stored in it somewhere. I understand, in theory, how it works, but that humans thought up and built something like it seems almost implausible.

That's why I get panic attack in mri machine

If only hospitals didn't charge an arm and a leg to use the device to everyone, we could properly detect issues.

In my organic chemistry courses we've used NMR (MRI without the imaging, just graphs) for identifying so many different molecules it's insane. I'll admit it's a pain to interpret but it will tell you exactly what is in a molecule and at how it's all connected. Tells you the location of individual atoms relative to others in the compound, it's insane. And it isn't just for water, it can be applied to any atom, normal isotope or not, that has an odd number of protons if I remember correctly. There's carbon NMR, chlorine NMR, hydrogen NMR, etc. It's incredible.

I'm a biomedical engineer student and when I first heard about the MRI machine I was instantly sold on what I wanted to do in the future. My professor explained that it might be the most difficult thing humans have ever achieved.

When I was at university, this was called nuclear magnetic resonance. The devices were originally called NMRI scanners, but they dropped the "nuclear" bit as they were concerned that people thought it was going to irradiate them and make them radioactive. Such is the effect the word "nuclear" has on the popular imagination.

NMR does not work on molecules the way that microwaves do, they interact directly with the nuclei of atoms. In the case of medical (N)MRI, it's the nuclei of the hydrogen atoms that are part of (mostly) the water and fats that are part of the body which are resonating. The different environments that those hydrogen atoms are in give different responses to the resonance scanning and it's that which is used to produce those images (after a huge amount of computer processing).

I recall back in my university days producing a little device in the lab for detecting NMR in samples. It was surprisingly simple, but then I was only looking for a signal on individual samples, not trying to make an image from it. I was just excited that I was directly interacting with the nuclei of atoms, which seemed quite exotic and much more exciting than just tearing electrons off atoms which happened in chemistry and electronics.

Mri found my brain aneurysm early enough to control it without surgery

[UMCPastorMNM]

I remember when I was working in a large hospital in the late 80's early 90's. MRI's came along and replaced something called "Exploratory Surgery".

The only downside to MRI is that it's expensive, takes almost half an hour to perform and it's scary for claustrophobic people.

[samuelanders]

I had an mri back in 2017 and spent a good chunk of time asking the tech questions about how it worked. Really fascinating stuff

[jojothetasmaniansassmonkey]

too bad insurance providers will do everything in their power to justify denying approval of a doctors MRI order....they always want you to get a cheaper (and more risky) ct scan first

[crazyburkey]

An MRI will definitely let you find out if you've got a phobia of tight spaces

Dr. Raymond Damadian was the inventor of the first Magnetic resonance imaging(MRI) with his company Fonar.

The MRI that scanned our head looks absolutely horrific for common people, but that's the reality. Plus, I was also shocked when I saw those eyeballs, LOL... 😂😂😂
