AIM OF THE STUDY: To develop a clinically relevant and qualitative brain magnetic resonance imaging (MRI) scoring system for acute stage @entity772 @entity1167 @entity1 . METHODS: Consecutive @entity772 post- @entity1167 @entity1 were prospectively enrolled. Routine brain MRI sequences were scored by two independent and blinded experts. Predefined brain regions were qualitatively scored on diffusion-weighted imaging (DWI) sequences according to the severity of the abnormality on a scale from 0 to 4. The mean score provided by the raters determined poor outcome defined under the Cerebral Performance Categories 3, 4, or 5. DWI scans were repeated after @entity2332 ( @entity2332 ). The same qualitative scoring system was applied and results were compared to the initial scores. RESULTS: Out of 24 recruited @entity1 , 19 with brain MRI scans were included. Of the 19 included @entity1 , seven showed a good outcome at hospital discharge and 12 @entity1 showed poor neurologic outcome. Median time from the arrest to the initial DWI was 166min (IQR 114-240min). At 100% specificity, the overall, cortex, and cortex plus deep grey nuclei scores predicted poor @entity1 outcome with a sensitivity of 91.7-100% (95% CI). Follow-up DWI scans after @entity2332 showed worse results than initial scans. CONCLUSION: A qualitative MRI scoring system effectively assessed the severity of @entity1545 following @entity1167 . The scoring system may provide useful prognostic information in @entity772 @entity1167 @entity1 .
