Evaluation of quantitative contrast harmonic imaging to assess malignancy of liver tumors: A prospective controlled two-center study

Figure 3 ROC diagram showing the specificity and sensitivity in the late venous phase for different limiting values (varying the cut-off values from +5 to -5). A greater distance from the diagonal line indicates that a diagnostic test had a higher reliability. The black point in the ROC diagram corresponds to the best sensitivity and specificity.
