Abstract
Magnetic resonance spectroscopy (MRS) is a non-invasive technique that can be used to measure the concentrations of different low- molecular weight chemicals. It differs from conventional magnetic resonance imaging (MRI) in that spectra provide physiological and chemical information instead of anatomy. The high diagnostic specificity of MRS renders the biochemical changes that accompany various neurological disorders detectable. It may also be useful in disease characterization, sometimes diagnosis, and monitoring. In this paper, we discuss the physical basis, normal spectra, clinical applications, and results interpretation of MRS in the evaluation of neurological disorder.
