Receiver operating characteristic (ROC) curves for DCE-MRI and MG. AUC, area under the ROC curve

The difference of the diagnostic performance employing receiver operating characteristic (ROC) analysis between MRI (AUC=0.904) and MG+MRI (AUC=0.941) was not statistically significant (p=0.53). The AUC for MRI was statistically higher than that AUC for MG (p=0.0052).

Abbreviations: MG, annual mammography alone; MRI+MG, bi-annual dynamic contrast-enhanced magnetic resonance imaging + annual mammography; MRI, bi-annual dynamic contrast-enhanced magnetic resonance imaging alone.
