What is Spectroscopy?

Spectroscopy is a noninvasive medical imaging technique that evaluates the chemical composition of body tissue (usually the brain). 

It usually uses an MRI scanner and it can help determine if an abnormality on an MRI image is a tumor and if so, what type. It can also be used to help identify changes caused by seizures or stroke. MRI spectroscopy uses the same machine as a traditional MRI, but with added tests, leading to a longer scan.
