Table 3.

Lesion categorization for computer-generated maps and positive predictive values, and 100 ml was chosen as an arbitrary cutoff value

Ischemic lesions	Lesions ≥ 100 ml
N = 143	N = 10
PPV = 6 %	PPV = 70 %
Infarct only lesions	Lesions ≤ 100 ml
N = 15	N = 205
PPV = 0 %	PPV = 6 %
Mixed (ischemic and infarct)
N = 57
PPV = 12 %
