DMV white matter injury severity scoring system

PointsScoring
Cerebral edema0–3None = 0, right or left = 1, bilateral asymmetric = 2, bilateral symmetric = 3
Corpus callosum0–31 point each for genu, body, and/or splenium lesion
Right cerebral WMScore each cerebral hemisphere region for punctate, linear, and/or cavitary lesions
    Frontal0–12Punctate: mild (1–3 lesions) = 1, moderate (4–6 lesions) = 2, severe (>6 lesions) = 3
    Parietal0–12Linear: mild (1–3 lesions) = 1, moderate (4–6 lesions) = 2, severe (>6 lesions) = 3
    Occipital0–12Cavitary: mild (1–3 lesions, <15 mm) = 2, moderate (4–6 lesions, <15 mm) = 4
    Temporal0–12severe (>6 lesions, <15 mm, or 1+ lesion >15 mm) = 6
