[NMR-intrascopy - new method of biophysical investigation].

During the past few years new techniques have been developed in nuclear magnetic resonance (NMR) which make it possible to form two dimensional cross-sectional images related to the distribution of protons in biological structures. The methods are non-invasive and of low radiation hazard and could therefore have some clinical value in medical diagnosis. Several methods of producing NMR images are discussed and examples of biological application are given.
