No. of subacute or chronic infarcts in the patient subgroups (defined on FLAIR imaging), their categorization as watershed or territorial infarcts, and the number of cases in which an infarct lesion was categorized differently after ss-pCASL imaging than with the standardized perfusion atlas
| Vessel Status | No. of Infarct Lesions/No. of Patients in Subgroup | No. of Watershed Infarcts/No. of Infarct Lesions in Subgroup | No. of Territorial Infarcts/No. of Infarct Lesions in Subgroup | No. of Infarct Lesions Differently Categorized by Using the Standardized Perfusion Atlas vs ss-pCASL |

| Unilateral ICA stenosis | 11/21 (52%) | 5/11 (45%) | 6/11 (55%) | 4/11 (36%) |
| Bilateral ICA stenosis | 4/9 (44%) | 2/4 (50%) | 2/4 (50%) | 1/4 (25%) |
| Unilateral ICA occlusion and contralateral ICA stenosis | 15/15 (100%) | 8/15 (54%) | 7/15 (46%) | 6/15 (40%) |
| Bilateral ICA occlusion | 3/3 (100%) | 3/3 (100%) | – | 0/3 (0%) |
