Hi alvok8
I'm sorry no one has responded to your question yet, i've been off line for a couple of weeks and i've only just had the opportunity to log on, it's summer over my side of the world (Australia)....
From what i understand your brain MRI results are saying the tiny-fine lesions that have shown up in the periventricular and cerebral white matter are suggestive-consistent with ischaemic small vessel disease, which could well be within normal limits depending on your age group and or medical history.
Hope that helps......JJ
