Magnetic Resonance Spectroscopy

Meaning

Magnetic Resonance Spectroscopy (MRS) is an advanced, non-invasive imaging technique that utilizes the principles of Nuclear Magnetic Resonance (NMR) to measure the concentration of specific biochemical metabolites within tissues in vivo. Unlike standard Magnetic Resonance Imaging (MRI), which provides anatomical structure, MRS yields quantitative biochemical data, offering a unique window into the metabolic health of organs like the brain, liver, or muscle. Clinically, it is used to diagnose and monitor neurological disorders, characterize tumors, and assess changes in lipid or energy metabolism, providing functional information that complements anatomical imaging.
