Magnetic Resonance Spectroscopy

Magnetic resonance spectroscopy (MRS) is a noninvasive diagnostic test used to detect and measure the concentration of specific chemicals in tissues of the brain and other parts of the body. It is especially helpful when dealing with cancers and other tumors, but it can also provide valuable information when caring for patients with issues like Alzheimer’s disease, autism, stroke, epilepsy and other neurological disorders.

By measuring the types and amounts of amino acids, lipid, choline, N-acetyl aspartate, creatine and other substances, MRS can determine the type and aggressiveness of certain tumors.

The test is performed by a radiology technologist in a hospital or outpatient imaging center. Like a Magnetic Resonance Imaging (MRI) scan, you will lie on a bed that is slowly moved into a magnetic field. You may be given an injection of contrast dye to enhance the pictures that are taken during the test.
