In Vivo Magnetic Resonance Spectroscopy
In vivo (that is 'in the living organism') magnetic resonance spectroscopy (MRS) is a specialised technique associated with magnetic resonance imaging (MRI).
Magnetic resonance spectroscopy (MRS), also known as nuclear magnetic resonance (NMR) spectroscopy, is a non-invasive analytical technique that has been used to study metabolic changes in brain tumors, strokes, seizure disorders, Alzheimer's disease, depression and other diseases affecting the brain. It has also been used to study the metabolism of other organs such as muscles. In the case of muscles, NMR is used to measure the intramyocellular lipid content (IMCL).
Magnetic Resonance Spectroscopy (MRS) is an analytical technique that can be used to complement the more common Magnetic Resonance Imaging (MRI) in the characterization of tissue. Both techniques use signals from hydrogen protons (1H), however MRI uses the information to create 2-dimensional images of the brain, and MRS uses 1H signals to determine the relative concentrations of target brain metabolites.

These metabolites include 1.) N-acetyl Aspartate (NAA) with its major resonance peak at 2.02ppm, decrease in levels of NAA indicate loss or damage to neuronal tissue, which results from many types of insults to the brain ... amino acids are marked by a series of resonance peaks between 2.2 and 2.4ppm ...
