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, ionizing radiation free 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).
