What is an MRI?
Magnetic resonance imaging (MRI) is a form of non-invasive diagnostic imaging that utilizes superconductive magnets and radio frequencies to produce detailed images of the anatomy that can be read by a radiologist to diagnose medical conditions.
How does an MRI work?
Unlike a CT scan, an MRI scan does not utilize X-ray, or any form of ionizing radiation, to produce diagnostic-quality images. The protons in your body are aligned with the superconductive magnet once you enter the bore. The radio frequency pulses interact with the protons and forces the protons into a 90-degree or 180- degree realignment for milliseconds at a time. Once the radio frequency is shut off, the protons return to alignment with the magnet. That motion is picked up by the receivers and mapped by the MRI to produce a vivid image of the anatomy.
