Active MS plaques on DWI b1000

MS plaques showing highest signal on b1000 are most suspect for activity - in my opinion. Therefore look at DWI (b1000) when reporting brain MRI of MS patients. 

Note the largest MS plaque (FLAIR left image) that shows typical peripheral enhancement (T1 C+ right image). You can also see other smaller plaques that do not enhance. 

Now observe that this plaque, unlike other, has high signal on b1000 (left image), without restriction on ADC (right image). Other plaques do not show such high signal on b1000. 

My point is that b1000 gives a clue to active plaques
