Figure 3 Receiver-Operating Characteristic Curves

(A) Receiver-operating characteristic curves for visual assessment of 1.5- and 3-Tesla (T) perfusion imaging for the correct identification of significant coronary artery disease. There was no significant difference in diagnostic performance of perfusion imaging between the field strengths (p = 0.23). (B) Receiver-operating characteristic curves for visual assessment of 1.5- and 3-T perfusion imaging for the correct identification of single vessel disease. The diagnostic performance of 3-T perfusion imaging was significantly greater (p < 0.05). (C) Receiver-operating characteristic curves for visual assessment of 1.5- and 3-T perfusion imaging for the correct identification of multivessel disease. The diagnostic performance of 3-T perfusion imaging was significantly greater (p < 0.05). AUC = area under the curve.
