The receiver-operator characteristic (ROC) curve comparing the diagnostic performance of CE-CCMRA and DS-CCTA for detection of x-ray angiographic diameter stenosis ≥50%. (a) The area under the curve (AUC) was 0.89 (95% CI: 0.79 to 0.99) for CE-CCMRA and 0.92 (95% CI: 0.83 to 1.00) for DS-CCTA on the patient-based analysis. (b) The AUC was 0.91 (95% CI: 0.86 to 0.97) for CE-CCMRA and 0.93 (95% CI: 0.88 to 0.98) for DS-CCTA on the vessel-based analysis
