Magnetic resonance imaging (or MRI) is a method that utilizes radio waves and a magnetic field to produce detailed images of tissues and organs within the body. Majority of MRI machines are big, tube-shaped magnets. When one lies inside the MRI machine, the magnetic field momentarily realigns the hydrogen atoms in the body. The MRI machine can also be used to generate 3-D images that can be viewed from several different angles.
