DMV white matter injury severity scoring system

	Points	Scoring
Cerebral edema	0–3	None = 0, right or left = 1, bilateral asymmetric = 2, bilateral symmetric = 3
Corpus callosum	0–3	1 point each for genu, body, and/or splenium lesion
Right cerebral WM		Score each cerebral hemisphere region for punctate, linear, and/or cavitary lesions
Frontal	0–12	Punctate: mild (1–3 lesions) = 1, moderate (4–6 lesions) = 2, severe (>6 lesions) = 3
Parietal	0–12	Linear: mild (1–3 lesions) = 1, moderate (4–6 lesions) = 2, severe (>6 lesions) = 3
Occipital	0–12	Cavitary: mild (1–3 lesions, <15 mm) = 2, moderate (4–6 lesions, <15 mm) = 4
Temporal	0–12	severe (>6 lesions, <15 mm, or 1+ lesion >15 mm) = 6
Left cerebral WM
Frontal	0–12
Parietal	0–12
Occipital	0–12
Temporal	0–12
	0–102	Global severity score
