MRI Brain Injury Scoring System
| Score | Findings |
|---|---|
| Basal ganglia/Thalamus | |
| 0 | Normal or isolated focal cortical infarct |
| 1 | Abnormal signal in the thalamus |
| 2 | Abnormal signal in the thalamus and lentiform nucleus (LN) |
| 3 | Abnormal signal in the thalamus, LN, and perirolandic cortex |
| 4 | More extensive involvement |
| Watershed | |
| 0 | Normal |
| 1 | Single focal infarction |
| 2 | Abnormal signal in anterior or posterior watershed white matter (WM) |
| 3 | Abnormal signal in anterior or posterior watershed cortex and WM |
| 4 | Abnormal signal in both anterior and posterior watershed zones |
| 5 | More extensive cortical involvement |
