MRI scan is an important diagnostic tool for Multiple Sclerosis. If anyone is interested, an excellent presentation given by FrederikBarkhof at the Neuroradiology teaching course for the Dutch Radiology Society and adapted for the Radiology Assistant by Robin Smithuis and Marieke Hazewinkel focussing on the role of MRI in the diagnosis of Multiple Sclerosis is available at http://www.radiologyassistant.nl/en/p4556dea65db62
It is an excellent presentation and explains how to differentiate MS lesions from other white matter diseases.
