NMR: dental imaging without x-rays?

Recently, advances in a new method of medical imaging have been reported by various authors. The method is based on the physical phenomenon of nuclear magnetic resonance (NMR) and is a well-established technique used in chemistry and physics. Radio waves are transmitted and detected in the presence of magnetic fields; the method is noninvasive and does not use ionizing radiation. The potential use of NMR in dentistry and basic concepts of NMR imaging are discussed.
