August 21, 2017

A diagnostic procedure which produces images of different body parts without the use of X-rays. Nuclei of atoms are influenced by a high frequency electromagnetic impulse inside a strong magnetic field. The nuclei then give off resonating signals, which differ in different types of body tissue. MR scanning is very sensitive to the inflammatory changes and scarring that occur in MS and is an important in diagnosis and in assessing the effects of new treatments.
