Infarct location classification by applying a perfusion territory atlas complemented by MRA clues as opposed to using T-ASL perfusion map

| Perfusion territory atlas+MRA clues | Ipsilateral ICA | BDZ ipsilateral ICA+BA | Contralateral ICA | BDZ contralateral ICA+BA | BA |
| Ipsilateral ICA | 64 | 2 | 1 | 0 | 0 |
| BDZ ipsilateral ICA+BA | 1 | 5 | 0 | 0 | 1 |
| Contralateral ICA | 0 | 0 | 19 | 10 | 4 |

BDZ indicates border zone between the stated vascular territories of the ipsilateral or contralateral ICA or BA. BA, basilar artery; ICA, internal carotid artery; MRA, magnetic resonance angiography; T-ASL, territorial arterial spin labelling.
