Magnetic resonance spectroscopy (MRS) is a flexible tool with real clinical utility. Examples from our experience in over 250 cases of clinical proton MRS are presented. Shorter echo time and reproducible water suppression increases the number of metabolites which can be detected and identified. Case reports illustrate the significance of altered ratios of N-acetylaspartate, choline, total creatine, myo-inositol, glutamate, glutamine, lactate, glucose, ketones, and, as an incidental finding, ethanol. Significant new information has resulted by applying proton MRS in chronic hepatic encephalopathy, diabetes mellitus and severe hypoxic encephalopathy ('near-drowning'). Potentially useful measurements have been made in normal brain maturation, ethanol related diseases, dementia (normal-pressure hydrocephalus), urea cycle defect and neuronal disease presenting as seizures. Metabolite imaging, particularly with proton, is clinically valuable, documenting the heterogeneity of biochemical disorders in seemingly focal lesions. A new method of specific 31-phosphorus--phosphocreatine imaging provides information in partially denervated skeletal muscle and is expected to have applications in brain.
