          Clinically isolated syndrome (CIS) patients experience 
						demyelinating events, without fulfilling the criteria 
						for clinically definite multiple sclerosis (MS). Here, 
						we investigated changes in lesions, normal appearing and 
						diffusely abnormal white matter in a CIS cohort using MR 
						frequency shift imaging. Over 2 years no changes were 
						observed in normal appearing and diffusely abnormal 
						white matter, while new MS lesions showed changes in the 
						MR frequency signal before enhancement, a steep increase 
						during their formation and elevated frequency for 12 
						months after lesion formation.
