Comparison of SVM Combining Quantitative Perfusion with Different Functional Parameters

	SVM
Parameter	TPD + ISCH + EFC	TPD + ISCH + MTC	TPD + ISCH + volumes
Sensitivity	84%	77%^*	74%^*
Specificity	88%	93%^*	94%^*
Accuracy	86%	86%	85%
ROC AUC	0.92	0.91	0.92

↵* Significantly different from SVM combining TPD, ISCH, and EFC, P < 0.05.
TPD = total perfusion deficit; ISCH = ischemic change.
