| Etiology of spontaneous ICH | MRI changed diagnostic category (n = 11.5) | MRI changed diagnostic confidence (n = 15.5) | MRI changed management (n = 14.5) |
|---|---|---|---|
| Hypertension (n = 25) | 1 (4%) | 5.5 (22%) | 1.5 (6%) |
| CAA (n = 10) | 2.5 (25%) | 2 (20%) | 4 (40%) |
| Vascular malformation (n = 7) | 2 (29%) | 2 (29%) | 3.5 (50%) |
| Neoplasm (n = 3) | 2 (67%) | 0.5 (17%) | 2 (67%) |
| Hemorrhagic transformation of an ischemic stroke (n = 3) | 2 (67%) | 1.5 (50%) | 2 (67%) |
| Illicit drug use (n = 3) | 0.5 (17%) | 0.5 (17%) | 0 |
| Coagulopathy (n = 2) | 0.5 (25%) | 0.5 (25%) | 0.5 (25%) |
