What does an MRI measure?
In essence, MRI measures the water content (or fluid characteristics) of different tissues, which is processed by the computer to create a black and white image. The image is highly detailed and can show even the smallest abnormality.
HOW IS MR spectroscopy performed?
MR spectroscopy is conducted on the same machine as conventional MRI. The MRI scan uses a powerful magnet, radio waves, and a computer to create detailed images. Spectroscopy is a series of tests that are
added to the MRI scan of your brain or spine to measure the chemical metabolism of a suspected tumor.
