METHODS: The study population consisted of 2164 patients who underwent 2416 consecutive brain MR imaging studies performed during 3 years. The severity of white matter hyperintensity on T2-weighted fast spin-echo images was graded as follows: absent, punctate foci, early confluent, or confluent (15).

BACKGROUND AND PURPOSE: More than 85% of brain traumas are classified as "mild"; MR imaging findings are minimal if any and do not correspond to P = .042). Patients with and without visible MR imaging pathology, typically punctate foci of suspected shearing injury, were indistinguishable in both atrophy and WBNAA.

The pattern of involvement in brain regions over time is relatively uniform as the disease progresses. Brain MRI or CT scans were performed in all patients (MRI in 89 out of 120, CT in 31 out of 120) and confirmed that territorial cerebral infarction, brain tumour or other structural lesions were absent.
