Receiver operating characteristic curves were used to evaluate diagnostic performance of MRCP alone and combined MRI for detection of PDAC concomitant with IPMN. A. For observer 1, area under the receiver operating characteristic curve (Az) was significantly improved in the combined MRI (0.964; 95% CI 0.922–1.006) compared with MRCP alone (0.834; 95% CI 0.753–0.916) (P < .001). B. For observer 2, Az value was significantly improved in the combined MRI (0.926; 95% CI 0.866–0.986) compared with MRCP alone (0.821; 95% CI 0.740–0.926) (P < .001).
