Figure 4.

Graph shows receiver operating characteristic (ROC) curve to see if there is any cut-off for the apparent diffusion coefficient (ADC) parameter for predicting malignancy. Area under the curve, which represents the probability the lesion, will be classified accurately as benign or malignant according to the ADC value, is 0.827. ROC curve analysis is suggesting that ADC ≤; 0.0011 indicates the possibility of malignancy in the breast lesion with 92.3% (95% CI 83.0 – 97.5) sensitivity and 73.9% specificity (95% CI 51.6 – 89.8)
