Magnetic Resonance Imaging
Magnetic Resonance Imaging (MRI) has rapidly become a powerful diagnostic tool-the diagnostic imaging method of choice in many clinical situations. It is based on magnetization of the various biological tissues. It does not use any ionizing radiation (such as x-rays) and is capable of direct imaging in any plane without reformatting. It can take multiple slices simultaneously. It can produce cross sections of the brain, spinal cord, heart, lungs, abdomen and blood vessels. In some instances it can chemically analyze body tissues by recording the behavior of atomic nuclei in living cells.
NMR Chemical-Shift Imaging (or Spectroscopic Imaging)
NMR chemical-shift imaging literally adds a dimension to the potential clinical utility of Magnetic Resonance. Not only images, but also chemical analysis of body tissues is possible through the use of magnetic resonance spectroscopy.
