Receiver Operating Characteristics Curves. ROC curves for CNR, SNR, and lesion size (length, area) as indices for discriminating between CMASS types. As shown, CNR yielded highest overall diagnostic performance (based on area under the curve [AUC]) for differentiating between CNEO and CTHR. AUC associated p-values reflect comparisons to null hypothesis (area = 0.5)
