[Future path of magnetic resonance spectroscopy in clinical medicine].

The metabolic exploration of skeletal muscle and brain by magnetic resonance spectroscopy (MRS) provides the basis of the main clinical applications of in vivo MRS on humans. Also, high resolution MRS is used in vitro to identify and assay the metabolites contained in physiological fluids (blood, urine, CSF). In these applications, MRS has became and will keep developing as the investigative tool of choice to perform non-invasively "live biochemistry" experiments on organs and tissues.
