a. "This test will help show whether tracts in your central nervous system are damaged."
b. "This test will measure changes in chemicals that transmit messages between your brain and spinal cord."
c. "This test will help predict what types of medication will be effective for treating your symptoms."
d. "This test will help your health care provider decide whether or not a computed tomography (CT) scan is needed to further diagnose your injuries."

DTI is a form of magnetic resonance imaging that produces detailed microscopic images of neural tracts and related injuries. It provides better imaging of subtle injuries than CT scans. It does not measure neurotransmitters.
