Authors' objectives:

This report describes the procedure of in vivo magnetic resonance spectroscopy (MRS), which usually uses the hydrogen or phosphorus spectrum, briefly discusses the precautions and risks associated with its use and examines the utility of its current diagnostic applications. The applications examined are primary muscle disorders, disorders of the brain, liver and heart, and cancer.

Authors' recommendations: In general, magnetic resonance spectroscopy must be considered an 'experimental' procedure. It cannot replace any currently available diagnostic test, and is not an 'established' diagnostic procedure in any condition or area. Currently it is not 'innovative' according to the accepted definition. Nevertheless, MRS has the potential to become innovative in certain clinical contexts. These are in the pre-operative assessment of patients with partial epilepsy and in the investigation of patients with probable muscle disorders. Although MRS is performed using diagnostic imaging equipment modified for the purpose, it is not a diagnostic imaging procedure. It should be performed and interpreted by those with the appropriate clinical and biochemical expertise in the areas or conditions being studied, and close attention should be paid to technical quality control to ensure valid results.
