[Topical nuclear magnetic resonance--a non-invasive probe for biochemical measurements in living organisms].

Topical Nuclear Magnetic Resonance (TNMR) is a noninvasive and non-hazardous new technique which allows local observation of chemical composition and metabolism in living objects. This article gives an introduction into TNMR, along with a brief discussion on instrumentation. Some clinically relevant TNMR results from literature will also be described and illustrated with our own experimental spectra of a forearm.
