Nuclear magnetic resonance in pathology: I. Principles and general aspects.
Nuclear magnetic resonance (NMR) has become established as a powerful diagnostic imaging technique in medicine. The power of NMR as a tool for characterizing molecular structure and for quantitative analysis of complex mixtures in the clinical laboratory or even in vivo is beginning to be exploited. In the clinical laboratory, NMR can analyze the complex mixtures of bodily fluids, intact cells, tissues, and their extracts. Phosphorus-31 or 1H NMR spectroscopy in vivo can provide a noninvasive probe of high-energy compounds, amino acids, and compounds of phospholipid metabolism. The basic principles of NMR spectroscopy are presented here, with emphasis on the various NMR parameters and the information they provide. A companion article presents a survey of applications in pathology.
