Comparison of the area under the ROC curve of three parameters (ASL-rCBF, DSC-rCBF and DSC-rCBV).

Indicators being compared	Estimate of the difference between the AUC	Standard error	95% confidence interval	χ2	P-value
DSC-rCBV vs. ASL-rCBF	−0.0569	0.0445	(−0.1441–0.0303)	1.6359	0.2009
DSC-rCBF vs. ASL-rCBF	−0.0681	0.0428	(−0.1519–0.0157)	2.5360	0.1113
DSC-rCBF vs. DSC-rCBV	0.0112	0.0131	(−0.0144–0.0369)	0.7342	0.3915

ROC, receiver operating characteristic; AUC, area under curve; DSC, dynamic susceptibility contrast; rCBV, relative cerebral blood volume; ASL, arterial spin labeling; rCBF, relative cerebral blood flow.
