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.

[@NatureSceneries]

This video does not explain the MRI in a correct way. The magnets do not “rotate” as shown in the video!! The radio waves does not move at the same rate as the magnetic field!! The radio waves are tuned to the hydrogens larmour frequency!!! H2O are paramagnetic, which means they have a certain amount of magnetic properties. By placing the body in this magnetic field, called B0, you can align most of the water molecules along the magnetic field direction, while some other molecules align in the opposite direction. In general, most magnets are in the 1.5Tesla range which means that the water molecules will “rotate” (spin) linearly with the strength of the magnetic field. At 1T, the hydrogen atoms will rotate at around 42.58MHz per second (called Larmour Frequency). That means, in a 1.5T, they will rotate at around 63.87MHz per second. The gradient coil will do a linear increase of the magnetic field (in XYZ axis) when a gradient echo is applied, for example, at feet end we might have a 1.498T, increasing the magnetic field along the body linearly, and the skull/brain might get 1.506T. Remember when I said that the hydrogen spins/rotate linearly according to magnetic field strength? By creating this variation in magnetic field along the body with the help of the gradient coil, we are able to “slice” the body. We use a radio frequency signal that is TUNED to the larmour frequency of each hydrogen atom, that means, if we want to read the water composition at the brain (essentially the tissue water composition), we send a RF signal of approx 42.58MHz * 1.504T = 63.955MHz. The water molecules that rotate at this frequency, will respond (excite) to this signal, other water molecules will not. When the radio wave is shut off, the water molecules will go back to a resting state and send out a signal. By creating different RF-signals tuned to the different larmour frequencies along the body, we are able to read the signal of each water molecule. That’s the function of the so called “body coil”. It acts as a transceiver, both sending radio waves and listening to incoming signals; like a big ear waiting for the hydrogen screams. ;-) This was the simple way, I am writing on my phone so my fingers are quite tired now. :-)

[@0ldw3lshm4n]

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.

(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!

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.

People must know why this is so expensive machine, and also that tehnology that stands behind machine is not rocket science, mather of fact, it is an very old tehnologie. But it is very interesting tech, beacuse, it is in a sphere of HyperPhysics, today there are some new materials that are in a state of Superconducting on much higher temperatures, cooled yust with liquid nitrogen (-196 c) ...(relatvly cheap gas).
