Sensitivity, specificity, diagnostic accuracy and inter-reader agreement Per-segment sensitivity, specificity, and diagnostic accuracy of QISS MRA with and without PDIP-SOS MRI and CTA for the detection of hemodynamically significant (≥50%) stenosis compared with DSA, as well as inter-reader agreement in stenosis detection (κ)

	Sensitivity (%)	95% CI	Specificity (%)	95% CI	AUC	95% CI	κ	95% CI
CTA	90.2 (93/103)	82.8–95.2	94.2 (98/104)	87.8–97.8	0.923	0.877–0.955	0.901	0.849–0.953
QISS MRA	85.4 (88/103)	77.1–91.6	90.3 (94/104)	83.0–95.2	0.879	0.827–0.920	0.832	0.756–0.908
QISS MRA with PDIP-SOS	92.2 (95/103)	85.2–96.5	93.2 (97/104)	86.6–97.2	0.928	0.883–0.959	0.855	0.786–0.925
