Magnetic Resonance Spectroscopy (MRS) is a non-invasive diagnostic technique that provides information about the chemical composition of tissues in the body. It works by measuring the magnetic properties of atomic nuclei, allowing for the identification of various metabolites in biological samples, which can be crucial for diagnosing conditions like tumors or neurological disorders. Unlike traditional magnetic resonance imaging (MRI), which focuses on structural imaging, MRS offers insights into the biochemical changes occurring within tissues. This makes it a valuable tool in both clinical and research settings, helping to enhance our understanding of diseases and their progression.
