How do MRI relate to eletromagnetic waves?

MRI, or Magnetic Resonance Imaging, utilizes strong magnetic fields and radiofrequency electromagnetic waves to produce detailed images of the body's internal structures. The MRI machine generates a strong magnetic field that aligns the hydrogen nuclei in the body, and then radiofrequency pulses are applied to disturb this alignment. When the radiofrequency is turned off, the hydrogen nuclei return to their original alignment, emitting signals that are detected and translated into images. Thus, MRI exploits the principles of electromagnetic waves to visualize soft tissues in a non-invasive manner.
