What is MRI?

Magnetic Resonance Imaging is the most advanced technique currently available for imaging the human body. It uses a magnetic field and radio waves which when processed through a powerful computer produce images of the internal structure of the body.

How Does an MRI Scanner Work?

The human body is made up of primarily of water and fat. Water and fat have many hydrogen atoms which make the human body approximately 60% hydrogen atoms. When placed in a strong magnetic field (a typical MRI scanner has a magnetic field 10,000 times as strong as the Earth's) the hydrogen nuclei line up with the field and spin. As they spin, these nuclei wobble on their axes, or precess. An analogy often used is to imagine a spinning top wobbling before it comes to rest. Whereas a spinning top,   precesses only once or twice each second, the hydrogen nuclei, however, precess at a rate within the radio frequency range. They are thus both receptive to and emit radio waves. The radio waves so emitted, when analysed by a powerful computer, allow the creation of an image of the internal structure of the body. Any internal injuries to soft tissues, muscle, bone, ligament or cartilage are well depicted on these images and allow a diagnosis to be made.
